THANK YOU!!! I’ve been waiting for this!!
Emm, Luxrender isn’t under add-ons. I’m on Windows 7 64 bit. I put it under the Blender Scripts directory, but it still doesn’t show up…
I apologize for all these comments but I got it working. Lol
Hi Chris, Hopes this helps Vista and Windows 7 Are quite simular regarding regarding folder locations mine is located as such
C:\Users\Steven\AppData\Roaming\Blender Foundation\Blender\2.55\scripts\addons
Also you will not be able to find AppDate without clicking the view hidden folders button located in the folder options under Organise/ Folder and Search Options/ view (tab) and its in the box under advanced settings.
Hope this helps and thanks for the great tutorial, although even though I am able to enable lux render within the pref’s and fiddle with the lux render settings it wont actually allow me to render??
If anyone else has vista or windows 64bit and the same issue and resolved can you let me know thanks.
****Lol just noticed you got it working but if anyone else is struggeling hope this helps.***
Steven I followed your advice obviously changing “Steven” to “Becky” but for some reason my ends at C:\…\Blender Foundation\Blender\2.55 as there is no AddOns folder in that directory. I’m not sure what is going wrong here.
-becky
man ive having trouble, hope someone can help. I open up C: Program Files / Blender Foundation / Blender / 2.55 then after that it says / python / lib then loads of folders and no scripts or addons… is there something wrong?
Hi Bradley, that’s actually the wrong location on Windows. On Windows it should be here: C:\Users\yourname\AppData\Roaming\Blender Foundation\Blender\2.55\scripts\addons
-Jonathan
Thanks Jonathan, i managed to find it, it was hidden at the time
- Bradley
Way to go Jonathan!
More and more people are realising the benefits of LuxRender everyday. This will be a well referenced tutorial I’m sure
Andrew, the whole interaction with LuxRender is totally different in this tutorial than in your “realistic kitchen” tutorial. Is it just a newer exporter?
That’s because I’m Jonathan and the tutorial you’re thinking of is not mine. That would be Andrew Price’s tutorial over at http://blenderguru.com. I am not sure which exporter he was using as I haven’t watched the full tutorial.
-Jonathan
Yeah, I know, that’s why I was asking Andrew….
Whoops, my bad. From the WordPress dashboard comments aren’t threaded and so I didn’t realize your comment was a reply…
-Jonathan
No worries (see what I did there?). :0) Great tutorial, BTW, Jonathan. I’ve been messing around with the “all plugins included” Graphicall builds of Blender, but I couldn’t seem to get LuxRender to work. Now I have some concrete directions to go by.
Thanks Jonathan, I’ve been waiting for this
Great tutorial, I’m sure it will help out many people!
I have a Windows 64-bit build of Blender on GraphicAll which includes the LuxRender exporter and renderer for anyone who wants a faster way to set it up here: http://www.graphicall.org/builds/builds/showbuild.php?action=show&id=1592
I highly recommend anyone having troubles installing go and get one of these pre-packed builds from graphicall
great! I did not know this! Thank you for the training.
It’s all about the render – thank you Jonathan!
By the way, where could acquire the wallpaper?
@Dobz Thanks for the blender 64bit with Luxrender build link.
Oops, I meant to say, “By the way, where I could acquire the wallpaper?”
I found it! It was one of the background images in the twitter profile design settings.
hmm. lux render isn’t showing up in user preferances… what do i do
First thing, what have you done so far and which version of Blender are you using? LuxBlend only works in 2.55 and later.
-Jonathan
i’m using version 2.55. i already installed lux render and extracted the .zip file to the script folder in blender 2.55.
then i opened blender and went to user preferences and add ons and lux render wasn’t there
Are you on Windows, Linux or Mac OS X? This will determine where you need to place the Addon.
thank you so much Jonathan for this lux render is working now
i waited for this, ´cause i downloaded luxrender several month ago – but didnt get it to work. thx a lot and keep up the good work.
Finally, thank you, thank you, thank you.
Hope this question is not too silly, but will LuxRender be of any use when baking textures? I don’t know much about this (which is probably obvious), but I assume baking uses a render engine, but will it use an external one if this is the selected one, or will it always use Blenders internal one?
RK
Nope, you can’t bake textures with LuxRender unfortunately.
Thanks for the reply, Dobz. Business as usual, then.
Oh, and thank you for the tutorials, Johnathan. Keep’em coming! Any ETA for the next part of the jeans texturing tut?
RK
What about environment maps. Is that straightforward to add into LuxRender?
If you mean sky textures and HDR maps, then yes they fairly easy to set up. If you mean the environment maps that fake reflections in the Blender renderer, then no you can’t use them.
Thanks for the tutorial.
Just a question: is it available network rendering for Luxrender?
Thanks again.
I believe network rendering in Luxrender is working but I wouldn’t quote me on that. I have not tried it.
-Jonathan
It is available and working, but you have to set it up from the LuxRender GUI, not Blender.
Incorrect, the lastest luxblend25 code has a LuxRender Networking panel in the render settings. Check the box and input a comma separated list of IPs or hostnames and it should work.
I never saw that before, good to know it’s been implemented into LuxBlend.
we’ve come a long way baby.
Thank Jonathan, sorry but I must be a bit thick or something as I really don’t understand how to install this on a Windows 32bit system. I went to C:Users/blahblahblah/Blender/gobbligoop/thingybob/wtf but I couldn’t see a 2.55 folder or any addon folder I shoved it in \scripts and it didn’t show up when I ran Blender so in messing about I managed to get the Blue Screen of Death! and had to reboot.
Please, please explain in the simplest terms possible how I can achieve this! Why oh Why don’t Blender simply make a normal Addons Folder like all of my other programs have?!! !!!!
-becky
Nevermind after searching through all my Blender folders I managed to paste Luxrender in just about every one
and now it’s working. Yay for inefficiency!
\o/ Becky
Actually it’s not working
Luxrender shows up in the AddOns, the Render Menu and I get the Luxrender options in the Render Panel – but when I run Luxrender following your instructions it starts but then ends abruptly after about 10 seconds. I have gone back to the AddOns Panel and if I unselect Luxrender it becomes greyed-out and is unselectable a second time only rebooting fixes this. I must be doing several things wrong here and I’m not stupid when it comes to cofiguring programs and addons but this is just driving me crazy.
-Becky
Hi Becky, sorry to hear you’re having trouble.. I believe the stopping may be caused by a lack of lights in your scene. Have you double checked that you have some kind of light source? I found if there’s no lights then you’ll get this exact behavior.
-Jonathan
I was using the default set up cube with the single light source – I would have thought that would have worked?
I have not been using the installer version of Blender via the Blender website but using the standalone newer builds from http://www.graphicall.org/builds/ but the problem persists.
I have also downloaded the installer version from Blender directly and that isn’t picking up the Luxrender module at all in my User Preferences/AddOns section despite installing to the correct addon folder via C:Users\…\Blender\2.55\Scripts\AddOns
*shrugs* such a pity Blender don’t work to make this stuff easier.
Looking in the AddOns section of User Preferences I can see that Luxrender is there but not working flagged with an error message stating *Missing Script Files I really don’t understand what is happening here but it’s clear this isn’t a finished item by any means.
Here’s what worked for me:
Download 2.55 beta (32bit) zip file from blender.org, extract to “C:\”. Download luxblend25 zip as described in video, extract to desktop. Copy the “luxrender” folder from “src” subfolder to “C:\blender-2.55-beta-windows32\2.55\scripts\addons”
Make sure you copy the “luxrender” folder itself and not the contents directly, so that it becomes a subfolder of “addons”.
Launch Blender from “C:\blender-2.55-beta-windows32\”, enable LuxRender in addons as show in video and select LuxRender as the renderer.
Check the “Run Renderer” as shown in video and enter the full path _to the directory containing luxrender_ (not the exe file itself). In my case “C:\Lux\Dist\64\”. When using the file selection dialog box doublecheck that “Relative Path” is unchecked! This is enabled by default on the version’s I’ve tried and will cause it not to work.
Select “LuxRender GUI” and hit “Image” button as shown in video and it should work with the default scene (doesn’t look very good tho).
If you still have problems feel free to ask in the official support thread: http://www.luxrender.net/forum/viewtopic.php?f=11&t=4516&p=50696
Hope this helps.
This was supposed to be a reply to Rebecca Fryer a couple of posts up.
have you set the absolut path to the LuxRender executable ?
Make sure you have “Path to LuxRender Installation:” set correctly in the render panel. That sounds like your problem. Good luck!
No it’s not that C:Program Files/Luxrender/luxrender.exe – checked all of that out and tried in different combos with setting it’s a no go. Perhaps it’s only working on 64bit systems?
Oh that may be your problem, you need to set the path to the directory of the .exe, not the .exe its self.
-Jonathan
hate video tutorials… couldn’t this be done as a serie of pics? It will take me more than 2 1/2 hours to see this with my connection, and as I have played some times with luxblender, materials and render settings, this could be just another introduction… well I’ll never know. sorry about all this, and thanks anyway man!
Thanks for the useful tutorial!
I have got a question that perhaps seems to be a little bit strange: Is it possible to run the 64-bit-Version of Luxrender together with the 32-bit-version of Blender 2.55 the way shown in the tutorial? The reason why I ask this is: I had the 64-bit-version of Blender 2.55 installed, but it crashed when I obtained a new graphics tablet whose driver only works with 32-bit-applications. So I changed to the 32-bit-version of Blender to be able to use the tablet in sculpt mode.
If you choose the External rendering type, as shown in the video, you can mix 32/64 bits for blender and LuxRender without a problem.
Oh, thanks a lot! I’ll try this out.
Gooey XD
Thanks for this tutorial! So no mention of the upcoming luxrender releases that do GPU acceleration rendering?
ahhh path to the folder not the .exe itself. i had to watch the video again am listen closely to the intruction lol, thanks for the video i’ve been tryna find a good tutorial on this but i could this helps, thankyou (no more appending my files in 2.49b for me
Ah yes this solved the problem here too – I was selecting the Luxrender.exe. But I still can’t get it to run on the Instalation version of Blender but at least I have one working version in the standalone version of the latest build.
thank you a lot
I waited for this tutorial since a half year!
Thank you
(sry for my terrible english (german))
F.V.
Thank you for all your tuts this is a great site!
Now this was timely!! Thanks. For some reason Luxrender will not work straight out of Blender 2.55 for me (I run Win 7 64 bit) but the exporter works great so I am not complaining. I have a major work rendering right now that may take a couple of days but already the result is better than anything I have gotten from Blender’s render engine!!!
Thanks for all the great Tutorials Andrew. I have never regretted becoming a Citizen member and will most likely be a Cookie for life!
Heh I believe you have the wrong person
Andrew is over at Blender Guru. But thank you regardless and best of luck with your project!
-Jonathan
@ Jonathan LOL I was being a bit dislexic in my comment and I did mean you althouth I follow both very carefully. Im 63 years old so I have an excuse for being ditzy!!
thanks!!!!
Oh wow. 38 comments in one day or so… can’t wait till I have time to watch this.
Personally, I do not like LuxRender because of the render times and the fuzzy look. Even at 25 min. it still is not very clear. Hopefully Blender will work on its internal renderer without giving the fuzzy look.
-AE
Dude try the GPU version….that will get you faster results. (pending you have compatible hardware).
Hey, also, I think you guys should combine websites. It may help others in search of tutorials, and both of BlenderGuru’s and BlenderCookie’s work is fantastic.
-AE
Hey Jonathan,
Becks and I seem to be having the same issue I had set up a light source I actually just posted a comment stating that this may be an issue but does not seem to have been posted.
Are you still having the problem after adding the light source?
-Jonathan
Yea, can’t help but feel there’s a setting im missing. I have everything working through the UI its just when I hit the render button Ill continue to play around with it. I watched a tutorial that Doug Hammond done stating about the light source so I was aware of it.
if you add the pylux.so in the luxrender/ addon folder, you can see material preview images.
next luxrender tutorial should be on how to optimize the rendering, KDTree etc, and when to use metropolis and not (indoor scenes outdoor etc)
Any chance of you going to show us how to use SmallLuxGPU anytime.
Thanks
Maybe if I can get it to work myself
-Jonathan
I’d like to learn (and use) cause I think a ATI Radeon HD 6850 would render pretty fast, right?
can LuxRender do SSS. What if you want global illumination and Subsurface Scattering. What would one do?
Not that I am aware of. However there is a new Matte Translucent material that you could use to simulate SSS.
-Jonathan
awesome…i was waiting for this too!!!!
hugs, thanks, praise, appreciation and cheers!!!!
Thank you so much Jonathan. Are you sure 26′ and 35” is the duration of tutorial? It seems it has been truncated! Maybe there is some problems?
Thank again,
enzo
This is th BEST luxrender introduction tutorial I have seen, especially since its for 2.55 and covers the setup of the files!
Really awesome!!!
I wonder when we set up the blackbody type texture for the highlight and overhead fill light blender chose the texture type as clouds by default wich we then override with chosing blackbody for the Luxrender preset. Does this mean that i can simply ignore wich texture type blender choses by default (unless i set the luxtype to blender texture of course), or should i take care to make this a black image map or something alike???
Anyhow huge thanks again!!!
and sorry for doublepost ;(
If you’re using a LuxRender texture type, it will override the blender type and it doens’t matter what it’s set to. The default Clouds will be ignored.
Hopefully in the future the addon will be able to replace the blender list completely and this will be less confusing – but at the minute it is not possible.
You can just ignore the default Blender texture
-Jonathan
I got another lil question:/
Are the luxrender material and light settings independent from existing blender materials, meaning is it possible to have both the blender-internal renderer materials and the luxrender material and light settings coexist withhin the same scene.
If not would anyone suggest to make a secondary instance of the whole scene on different layers each with its own set of either Lux or BI material and lights?
I wondered since i would want to preview my scene with the blender internal and then just fire up Luxrender at will with the materials i set up for the luxrender use.
I dont know how to say it, basicly i wonder if i can work in the same file with sorta 2 sets of materials set up(blender and LUX) without having to repeat all the settings over and over again if i modify my scene with new objects or stuff?
Yes, the LuxRender settings are stored additionally to the blender settings in materials. The exception is the main colour, which LuxRender overwrites in order to set the object colour in the 3D view.
Thank you very much for your replies!:)
Great thing with both the blender default texture and the material settings, this will make it easier to tweak scenes while still being able to switch the renderer type freely. Awesome-o!
Thanks again for your effort with Luxrender and your quick response! LUX ROXX!
Greetings from Berlin
Man this is BIIGG… Thanks very very much!!
If I would be LuxRender developer, I would make 1 page on my site with all the latest files needed to download.
Now it’s FAR too complicated.. don’t they really understand that?
The reason it is “difficult” to download/install is because it’s under heavy development. It is our goal to integrate LuxRender with the Blender Addons so you can download and install LuxRender directly from within the Addons panel in Blender. However this will have to wait until Blender settles down a bit.
If you check out our official release versions you’ll find it’s very easy to install (against Blender 2.49).
We are aware of this, and we have a new website in the works which will be published when it’s ready
Oh I am quite interested in seeing this when it’s available. Thanks for you input here dougal2 and of course all your excellent work on the exporter.
-Jonathan
Also, just if anyone wanted a comparison to see how powerful Luxrender is.
Both these images used similar lighting, similar materials etc (Obviously i coudnt get them exactly the same…)
This is the result of 4 hours rendering in luxrender :
http://nl.tinypic.com/r/2djxrud/7
And in blender with AO, SSS and reflections in 2 minutes 40 seconds :
http://nl.tinypic.com/r/qzq8b7/7
I think we can all see which result is superior. Though the realism does come at a price…
Also, any pixels left in Luxrender can easily be fixed wit the simplest of programs such as paint..
how would one use the goodness of global illumination and SSS scattering that blender provides all in the same render? Any ideas or is that not even possible. Or is it built into LuxRender as well?
eventually LUXRENDER STARTED.
you people can’t even guess how excited I am right now
it took me 2 hours to get luxrender even started. And I can’t even get luxrender work internal in blender… (something called pylux didn’t work (wasn’t the right infrastructure (32/36bits)))
thanks anyway.
you helped with the part to get me to know I shouldn’t install blender with an application directory as stuffdepository but the blender folder itself
OMG!!! I was trying to install luxrender yesterday (and i failed miserably) and now, you posted a tutorial on it!!!! Many thanks!!!!!
Hey Guys,
thanks for sharing your knowledge Jonathan. Saved me alot of time try to setup Lux in Blender 2.55.
Here´s my result after 4h rendering on 8threads:
http://stiemo.st.funpic.de/zeug/hdm.png
Saved me much time in setting up the right light and AO settings in Blender, than starting rendering and go in the restaurant. Come back and have a nice Pic
Hey that looks really nice and clean Timo Ruoß! Nice work.
-Jonathan
k, im on a imac, and i open up the add on’s menu in the user preferences. LuxRender is there but i cant check the box off. Anyone know how to check it off?
Thanks Jonathan. Well explained.
Is it my comp or is the portal material (as suggested on the lux wiki to streamline rendering) missing on this recent build?
Anyone got a hint..i can’t find it in the material or texture presets.
‘Portal’ never was a material. In this version of LuxBlend25 it is a mesh option.
Thanks again:)
Think i found it now with that hint!
I read through the wiki page about portals and i think this sentence got me the idea that it coud be found with the materials.
‘To create a portal, just create a rectangle with its normal pointing inward in all window openings and assign the portal material. ‘
Thanks and cheers:)

EXCELLENT! Great Tutorial and easy to follow, Thank You!
Hey, I managed to install it properly…. or so I thought, but when i try and activate it in the blender preferences the check box won’t work. I have had this problem the last time i tried to install it too. I’m running Blender 2.55 on mac osx 10.6. Any suggestions?
Okay im using a mac like you Jonathan, and i get luxrender in the addons and everything is how you did it, but when i press render i just get the black image as if its about to render but nothing happens. help pls
This most likely means you don’t have a lightsource in your scene or you incorrectly set the path to LuxRender. The path needs to point to the LuxRender directory, NOT the executable.
-Jonathan
I am having trouble with trying to put image textures. Help!
Be sure to set the mode to Color rather than float.
-Jonathan
I did but it still does not want too work. It just stays gray
Oh nevermind, found out how to do it
Wow! Can you do more tutorials with Luxbled25? For example, how to make a bump texture?
Got it working on windows 7 32 bit… thankyou for the tutorial
It’s pronouced Mac OS TEN, not EX. X = 10.
I’m pretty sure it can be pronounced both ways…
I’m pretty sure most people learned their roman numerals in like, second grade, so there we go.
Nope, it is pronounced Mac OS TEN. Type in “say mac os x” in the terminal on your mac and it will say ten, not ex.
I downloaded the files ok, but when i went to my /blender foundation/blender/2.55/ folder there was only a python folder and no scripts folder! im using windows 64 bit is the scripts folder somewhere else or did i install blender wrong?
disregard this, i looked in the wrong place.
I have the same problem but now i don’t know where to look, where was yours?
Super helpful tutorial, definitely one of the more useful one’s i’ve found on here (which is saying a lot because of all the high quality tuts you put out)! I’m a member on and off, I’ll continue to support your efforts whenever I can afford to do so.
I would love to see more tutorials on external renderer’s, lighting and materials. Those are the areas that would help me the most in my blender production! But I’m sure whatever tutorials you do put out will be extremely helpful.
Thanks for the high quality training resource!
I installed everything correctly but when I hit render, it acts like its doing something but never renders. I need help!
Smith, please make sure you have a light source in your scene and that the path to LuxRender is set to the LuxRender directory, NOT the LuxRender executable.
-Jonathan
i want to use this to be able to sell my models online would it be wise to use a biased renderer until it becomes stable?
If it’s able to produce the results you want now then I would not worry about waiting. Just be aware that it’ll be prone to crashes.
-Jonathan
I have a question though I made a new record luxrender keeps the record of the scene above is how I fix the problem ?
Is there a way to create a scene without starting with Luxrender when modeling, and then just render with it afterwards? I cannot get previous models or scenes I have set up to render with Luxrender. Thanks!
I would guess you can’t enable luxrender in your old project files because it was started with a different default load. For all your old projects you probably need to go back into user preferances and enable luxrender in your addons.
Thanks a lot for the detailed instructions. Trying to play a bit with luxrender right now but after 4min of rendering there’s still only a black picture. Must have done sth wrong.
Is there anything like this for yafray? detailed install-instruction and a first overview?
Thanks again. Great tutorial.
Like many others here, please ensure you have a light source in your scene and that you have set the LuxRender path to the directory of LuxRender, NOT the LuxRender executable.
I hope that helps!
-Jonathan
P.S. I don’t know of any similars tuts for Yafaray…
thanks a lot. I’ll recheck. Didn’t have the patience yesterday to redo the tutorial.
Got this to work fine on Mac at work. My Windows 7 is giving me some trouble. It’s probably something silly easy, usually is.
Going to render i just get the black 3sec render as if Luxrender is not connected.
Path to Luxrender is set to Luxrender directory not executable.
Tried adding new lamps, giving meshes light emissions, nothing.
Installation should be fine since i have all the settings and can enable it as renderer.
Awww, the brain jello! It consumes me
Blender 2.55
Wibndows 7 64bit
Having same problems as shibazz.
Same CPU and OS.
Can’t figure it out.
Works for the GUI. But I can’t see updates in Blender.
imagin if someone try to do an animation with the lux render, XD he have to be crazy,
Good Morning!
I am a Design student from the Philippines (yes, your influence reaches the other side of the world), and I am very happy to have found blendercookie.com. Congratulations on your tutorials. You guys make one of the best references available out there.
This tutorial on LuxRender has been very much appreciated, Mr. Williamson! Photo-realistic images are now just a render time away!
Thanks a lot!
PS. I hope this tutorial can be updated as LuxRender is also updated.
Dropping a seed… Good news OpenCL and new build with Luxrender and SmallGPU, etec
The tweet with links: http://twitter.com/whimsycoll/status/4116442505023488
The Window builds:
http://www.graphicall.org/builds/builds/showbuild.php?action=show&id=1536
> Windows 64 bit
http://www.graphicall.org/builds/builds/showbuild.php?action=show&id=1525
> Windows 32 bit
Apparently filiciss builds have a lot more features to offer and add-ons ‘O.o`
Thank you Jonathan for this introduction to LuxRender 2.5 software.
After that, I’m definitly sure that I will become a citizen the next year. Blender cookie is the web site that I needed. I love this site.
Another idea of subject could be “How to parallelize the rendering process with yours old machines”. Parallelize trough the cloud, or a local cluster. Just to divide your time rendering by 2 or more …
Something like a technical tutorial in the same spirit that this guy who made a cluster in his HELMER (IKEA’s cabinet).
I placed the folder in the blender part and it’s showing up in the settings window. But when I click the box it won’t check
alright nm, I was using blender 2.5.4 thinking that it would work but you have to have 2.5.5
Another fantastic tutorial, Jonathan! Thanks for all of your time and effort to the Blender community. Unfortunately, I could not get LuxRender to render inside of Blender 2.55 BETA. LuxRender installed okay in the add-on and I have Blender pointing to the folder where LuxRender resides; not the executable. I also have 3 lights set in the scene. I am able to render in LuxRender if I click on the image icon to export and then open up the file manually in LuxRender. This works, but it would sure be nice to be able to figure out how to get it to render within Blender. FYI: I’m running 64-bit Windows Vista. If you have any suggestions, I’d really appreciate it.
Thanks again for all you do!
I’m having the same problem as “Yousif” and (possibly others, as it isn’t always easy to interpret exactly what problems people have from their descriptions)
I’m on Vista ((and Yes it suxx)).
I’m running Blender 2.55 “without installation”, i.e. I just unpacked the archive and run it from there.
I installed LuxRender as per instructions in the tutorial and tried to Use it, with the following “mixed result”.
Luxrender starts fine and renders, both in “GUI” and Console mode, but the “picture” in blender doesn’t update!!
In Blenders “Rendering statusbar, I get the following error message:
“[Lux 2010-Nov-16 13:19:10] ERROR: Could not load render result from untitled.Scene.00001.exr”
And in Blenders “console window” it says:
“[Lux 2010-Nov-16 14:32:11] Updating render result 384×216
[Lux 2010-Nov-16 14:32:11] ERROR: Could not load render result from untitled.Scene.00001.exr”
And if I look in LuxRenders “log” it says:
“[2010-11-16 13:49:21 Info: 0] Writing Tonemapped PNG image to file untitled.Scene.00001.png”
And it does indeed write to a png-file, this file is “placed” in the “root” of the drive where Blender is running.
And when i close LuxRender, Blender stops its “rendering”, so the “integration” seems to work.
But why does it say it tries to load a “.exr” file?
My render settings are to render to Png, but I tried using “OpenEXR” and nothing changed, I have also tried to change the “Output” path in the “render settings” but all to no avail.
I suspect this has something to do with the “paths”so that Blender is “looking in the wrong place” or “privileges” but I haven’t been able to get it to work yet.
All my “paths” in blender “user preferences>>files” are empty, except the one for “temp” which is “automatically” filled in with my “windows profile temp path”
Any suggestions as to what might be wrong, and how to fix it.
Me again
Just wanted to point out that the different “time stamps” in my examples has nothing to do with the problem. I just copied the different messages at different times during my trials, hence I got the different “time stamps” in the “log outputs”
And ooh I almost forgot again…
Thx for a great tutorial, or another great tutorial I should say
Just me, Yet again (well nobody else seems to care, and “The plot thickens…”;))
I installed the “PyLux” mentioned in “Tim Dickens” post here below, just to see what happened.
)
And low and behold, with Pylux installed I can now render internally, And so far everything seems “ticketBoo” (= AOk, except for the odd crash now and then
I.e. I can under “LuxRender Engine Configuration” choose “Rendering Mod>>Internal” and then the “LuxRender Result” shows up “within Blenders normal windows” no problems
But if I choose “Rendering Mod>>External” ((as I had to do before)) everything is as before. I.o.w. the rendering works, but the window in blender doesn’t update, and I get the same errors as before.
But when rendering with “LuxRender Engine Configuration>> Rendering Mod>>Internal”
I found the “Blender console” output “intriguing”.
I got the following output in Blenders “console window”:
“Snip ((Excluded the initialization for brevity, just included the “interesting lines”) snipp…
“[Lux 2010-Nov-16 18:53:15] Updating render result 384×216
[Lux 2010-Nov-16 18:53:18 INFO : 0] Writing OpenEXR image to file untitled.Scene.00001.exr
[Lux 2010-Nov-16 18:53:18 INFO : 0] Writing Tonemapped PNG image to file untitled.Scene.00001.png”
See!!! now it actually writes a “.exr” file, and this without any changes of my rendering settings ((compared to when rendering with “external” that is )) !!??
I.e. I still have set PNG as the “Format” under “Output”…,but it actually doesn’t matter which “Format” I choose, it always just “writes” the “OpenEXR image” AND the “PNG image”.
This behaviour surprised me, but sadly made me non the wiser .
And I still want “everything” to work, not least using “the external GUI” for the “postRender lighting flexibility” it offers .
So I posted this “wrinkle”hoping it might give some of You “BlenderHeads” out there to yet another clue as to what is actually going on here.
And that You hopefully can help me and all other noobs to get these things working
here is where to find pylux for window os. Pylux allows you to see the material you’re adding in the materials view port.
http://www.luxrender.net/forum/viewtopic.php?f=30&t=4457
If you want to use Pylux with LuxBlend25, you need the Python3 version, and it needs to go in \2.5X\scripts\addons\luxrender\
I copied the python 3 file not the folder to the luxrender folder and seems to work great.
Thanks for a great tutorial
hi. thanks for another great tut.
I’m running Win XP, Blender 2.55 and the latest Luxrender release. When rendering, materials assigned to the plane is not picked up by luxrender. I have assigned the texture in the diffuse color field.
any hints are appreciated
Martin
Hi,
Is it possible to an object to have multiple materials? When I try it, it seems that luxblend uses material that I have currently selected in the materials list for the whole object (I have assigned faces for different materials ofc).
Different colors can of course be handled with texture and UV mapping the object but what if I need different material-specific properties (specularity etc.) for different parts of the object?
Couldn’t find answer from the luxrender wiki/forums. Or I am just way off here as in having multiple materials for an object isn’t the way to do things with luxrender?
-Antti
From my understanding you can assign multiple materials just like you would in Blenders internal renderer. I am not positive on this though as I have not tried it.
-Jonathan
hi Antti,
I stumbled across this note in the LuxBlend manual:
IMPORTANT: Currently, LuxBlend25 ignores material face assignments, the material exported will be the one you had highlighted in the material editor! Make sure you have the mix highlighted, not one of the components!
Martin
Hi,
Thanks. Here’s the whole text:
“If you are creating a mix material, you must choose its components from existing material indexes assigned to that object. So any object that has a mix material will need at least 3 material slots: the mix material, component 1, and component 2. The 2 components need not actually be assigned to any faces on the object, they merely must be assigned to the object’s datablock.
IMPORTANT: Currently, LuxBlend25 ignores material face assignments, the material exported will be the one you had highlighted in the material editor! Make sure you have the mix highlighted, not one of the components! ”
Has anyone got a clue what this means in action. I’m lousy at Blender terminology so to me it’s “you need BLAA with BLAA and then just set BLAA to BLAA…”
So basically: How to create that “mix material”? And how to assign the component materials to right faces if face assigning is not supported?
-Antti
hello! can somebody help me I do all the stuff but it doesn’t work with 2.54 and if i use 2.55 the gui works but it doesn’t render!
Hi,
If none of the suggestions above have helped you can always export a .lxs from Blender by going to File > Export > LuxRender Scene. Then you can open this in the LuxRender GUI and render away.
-Jonathan
Hello.
I have a bad problem.
The script folder is missing. Anyway I created the folder and copy the luxrender folder to this folder. But whene I open the Addons panel in Blender. The luxrender option to active, isn’t in the selection panel.
I’m using Win 7, And Blender 2.55.
Please help me. T_T
Hi Fero,
If you are using an installed version of 2.55 then the script folder should be located under C:\Users\username\AppData\Roaming\Blender Foundation\Blender\2.55\scripts\addons or something similar.
If you are using a extracted .zip (portable) of 2.55 then you should be able to find the scripts directory in \blender directory location\2.55\scripts\addons
I hope that helps.
-Jonathan
Hi, i am trying to make an animation using luxrender and blender 2.55.
I have set the maximum samples to 16 and the render stops as planned, so far so good.
But how do I make it render the next frame automatically without having to manually close the luxrender GUI window?
Please reply,
Daniel Creese (riftmaster)
Hi riftmaster,
I am not positive on this but I believe you have to do it manually for the time being. If you check out the development releases in the http://luxrender.net forums then you’ll find a new Queue feature that should make it slightly easier.
-Jonathan
And to my question? because when I made a record with luxrender it gives me before rendering done with the blender internal rather than calculated a new image with luxrender
How it completely removes the grain on the image in luxrender because I can not get a clean image and net?
The grain is slowly removed as the image renders overtime, constantly improving the quality. If you want a grain-free image you will have to let it run for quite some time. This is one of the downsides to LuxRender (and other similar renderers).
-Jonathan
This goes to all Windows 7 Users:
If nothing happens once You hit F12 although You have selected the right executables directory, You might have a permission problem. Your blender console will have a corresponding line somewhere.
Running blender “as Administrator” should fix this, at least it did for me.
Cheers from Germany.
Thanks for this intro to LuxRender! This also served as an intro to external rendering software for me, and the quality/process differences.
I’ve been creating a model of a Christmas theatrical stage set, so I rendered a still from Blender and from LR for comparison.
I found Luxrender not only awkward to install and get operational, but difficult to use. Also, Luxrender crashes Blender after about 90 minutes, which leaves the still a bit noisy. And like some others, I could not get the external rendering to happen, but could render Internally with Pylux.
Take a look:

Again, thanks!
yeah the blender one looks way better
is it normal that when you export the scene to luxrender that none of the materials show up? it just showed my scene in black and white when i had image textures and such on it
Assuming your materials are setup correctly in LuxBlend then they should show up fine in LuxRender. Are you able to render from Blender fine?
-Jonathan
Ok so everything installs fine, but luxrender doesnt show up in blender at all. Ive tried old builds too, doesnt work.
Any help?
Where did you install LuxBlend to?
-Jonathan
helllllp nothing turns up when I render Even when I test it using blender render I can’t see my main charecter
hhhhhhhhhhhhheeeeeeeeeeeeeeeelllllllllllllllllllpppppppppppppp
what do you mean by luxrender folder?
I chose c:/program files/luxrender, is this the right folder?
if yes it doesn’t work for me, I got 2 lightsources but the screen is still black…
even the exporter doesn’t work, when I try to load it into luxrender it says:
“Parsing error in file ‘Lux test.lxs’ at line 3: syntax error”
in blender it says ecported succesfully
hm I think it’s a exporter problem, because with 2.49 it works
but how do I fix it?
I installed everything as you said, so I have no idea why it doesn’t work
running vista 32 bit: installed Luxblend dropped the luxblend folder in .blender\scripts started blender there is nothing in user preferences, add-ons render except default Any suggestions??
Thanks a lot ! Very helpful !
Here is my first attempt using Luxrender =)
http://img839.imageshack.us/img839/9999/luxrendertest3.png
don’t worry hadnt watched full thing sorry
Hi, great tutorial! I can’t wait to try it out. When I install LuxRender on Windows 7 it prompts me for the location of the Blender 2.55 scripts folder which is in \user\app data\roaming\blender foundation\blender\2.55\scripts\ It correctly installs the LuxBlend_0.7.1.py script there and I copied the luxrender dir to the same location, however Blender cannot find the add-on.
I also tried (crazy, I know) installing LuxRender 0.71 to the .blender directory in the same app data path, and as well to the Blender dir under Program Files, and copied the luxrender dir to both locations also. I had to create a scripts dir in the Blender dir under Program Files because (obviously) the Blender 2.5 install does not create one. In any case, this also did not work. I suspect there’s an issue with the path setting, however at no time did the LuxRender installer prompt me to set up a path – it just gave me the option to browse to the Blender scripts dir.
Your help is greatly appreciated. Please email me when you can!
Further to my issue, the following appears in the Blender console:
addon_disable LuxBlend_0.7.1 not loaded
bpy.utils.addon_disable LuxBlend_0.7.1
I’m not sure what I did that provoked that message since LuxBlend does not appear anywhere in the render prefs in Blender.
Sorry to keep replying to myself, but hopefully this helps other people. Turns out the py file and luxrender folder both need to be in the addons folder in the scripts folder. Not sure if I missed that in the video or what. Anyway, that gets me at least as far as Blender being able to see the LuxBlend addon, however now I am stuck at not being able to actually select it (the checkbox is disabled or something).
Hi rbtroj,
It sounds like you are trying to use the LuxBlend version that is packaged with LuxRender? Is this correct? This version is only for 2.49, as the 2.5 version is still in beta and so has not been bundled with it yet. You can download the 2.5 version from here: http://src.luxrender.net/luxblend25
Just click the “Zip” link at the top to download it. Once you have an unpacked copy on disk, you should see a folder called “src”. Inside this folder, there is a folder called “luxrender”. Copy this “luxrender” folder into your /addons/ folder.
I hope that helps!
Okay – after restart it seems to be working though throwing a lot of errors in the console. Oh well.
If anyone can’t get their LuxRender to work, I am willing to help. I went through some trouble at first, but I got it working at the end.
You can add me on MSN (use_of_power@hotmail.com), or Skype use_of_power
Also, thanks for the tutorial.
Hi, I followed the instructions, LuxRender appears in the Add-ons. But if I click the checkbox to activate it, NOTHING happens. What is up?
Well, the above problem solved, I installed python3.1. But I cant seem to get LuxRender to start…I HAVE set the path to luxrender, not the file. What is going on?
Does LuxRender start but fail to render or does it not start at all?
-Jonathan
Hi everybody! Up to date tutorial on Luxrender with Blender 2.55. Very nice and thank you Jonathan!
On the other hand I’m missing the emission button to use a mesh as a light source. The renderer is working fine but I need to add a blender light (spot, etc.) to the scene to see anything. I added a blackbody texture to my plane but no emission options (= no light if I remove the blender light). What am I missing? Thanks for your help. FloSo
HELP!!! I am trying to set up a lamp, but when I select “null” as a material type, there is no option for “Use Emission” Any idea why this is?
Well I finaly found the checkbox. It is located at the object tab. Please see http://www.blamenet.de/img/emission-found.jpg. Also see http://www.luxrender.net/forum/viewtopic.php?f=11&t=5028. Greetz FloSo
Great tutorial!
One question: I pasted the “luxrender”-folder into the scripts directory. In blender, I can see it in the user preferences but it is disabled. When I click the checkbox, nothing happens. Same thing happens when I use the TheaRender-demo.
What did I do wrong? How do I fix it?
Did you put in the addons folder within scripts? Also which version of Blender are you using?
-Jonathan
I’m currently using 2.54. Yes, I put it into the scripts-folder. I’m right now trying again after removing all Luxrender-data. Tell you if it worked this time.
Ha, I really should listen more carefully: I’m using 2.54, a blender version prior to 22.10.2010, so the extensions_framework isn’t included. I installed it afterwards and it works fine.
Hi, I can’t get the export script to work.
When I load a new blend file and go to user prefs, I can’t enable the LuxRender script (even though it appears). Where as if I load the blend file included with the download of this video, I can enable the script, but when I click “Image” to render it doesn’t come up with the exporting box that is seen in the video. Then it runs for about 2 seconds then finishes.
Cheers
Kieran
oh. my. god. my scene has been rendering for 45-50 minutes (it’s similar in setup to yours, Jonathan) and it looks….amazing. I’m definitely going to be using this for my next project…
Thanks for the great tutorial, Jonathan!
how long will it take to render 750 frames on a fast pc
In short, quite a long time in LuxRender. Unfortunately there is no single answer to that question. The render time depends entirely on the speed of your computer, the complexity of your scene and the setting you are using for the render.
-Jonathan
I m doing an animation for my class assembley please answer
thanks!! what about network rendering in luxrender would that narrow it down as my dad has a faster pc I mean fast fast how would that work.
Sebastian did a tutorial on this already, you can find it here: http://www.blendercookie.com/2010/12/12/network-rendering-with-luxrender/
Cheers!
-Jonathan
thanks how can I get yafray to work with blender 2.56/2.55 in windows just incase sorry if i’m pestering you
Hi Johnathan,I cannot seem to get luxrender installed properly.I have Win.7 64 bit home premium with both 2.49 and 2.55 beta installed(well just upgraded 2.55 to 2.56)but when I go to my blender foundation folder for the newest beta version I only have folders for python,any suggestions,I apologize if I missed it in the previous comments.I attempted this with 2.55 beta and 2.56 beta,and still can’t find the proper folders.
Hi hallowedking,
A lot of people have had trouble getting LuxRender to work correctly. My suggestion if you’re having trouble is to go ahead and use one of the weekly testing builds of LuxRender and a Blender build from Graphicall that is precompiled with LuxRender. I’ve included the two links that should work fine here:
LuxRender: http://www.luxrender.net/forum/viewtopic.php?f=30&t=5126
Blender: http://www.graphicall.org/builds/builds/showbuild.php?action=show&id=1536
If you still have trouble with these then feel free to submit a support ticket to support@cgcookie.zendesk.com
-Jonathan
I am feed-up with not being able to make a object, not a lamp, emit light I HAVE BEEN TRYING ALL NIGHT TO FIND OUT HOW AND I CAN PLEASE HELP I AM USING WINDOWS 7!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!11
Hey, I’m sorry to hear you’re getting frustrated. When in doubt the LuxRender forums HERE are a good place to look for things like this. There is a thread HERE that mentions the emission feature being moved to the Object properties. If you check any newer version of LuxBlend you’ll find this is the case. To enable it select your object and then go to the Object Properties and click the “Use Emission” under the “LuxRender Emission” tab.
Cheers and good luck!
-Jonathan
thank you so much!
Hay this is really getting me mad when i go into blender to select lux as an add on it will not let me select it i even tried the latest version of blender an did all that you said to do please help me.
btw i have a macbook pro with snow. if it matters
Which version of LuxRender and LuxBlend are you using?
-Jonathan
Hello,
i got a problem to start Rendering. when i hit F12 to start rendering i got this failure:
Info: Creating LuxRender context

How can i fix that?
Hi Frank, this sound like a compatibility problem between the version of Blender and LuxBlend. Which version of Blender, LuxBlend and LuxRender are you using?
-Jonathan
I’m using Blender 2.56 r33949, LuxRender 0.71 and LuxBlend2.5.
When I export the scene as *.xls it will run in LuxRender.
i do not know but can you send me all of the files you are useing you can send to tiny.baron111@yahoo.com
Finally got luxrender installed properly with min.7 64 bit,the issue was that when I got blender I got the installer version and I did not have a scripts folder,I uninstalled and got the newest beta zip instead of installer and now have the folders needed,not sure if that was mentioned anywhere but for anybody else that can’t find a way to install it with win.7 64 that might be the issue.
Hello hallowedking,
you can find the Scriptsfolder here:
C:\Users\”NAME”\AppData\Roaming\Blender Foundation\Blender
Yeah I got luxrender installed now,thanks though,I know where the folder was but mine didn’t have the scripts folder or any other folder,only python,so I uninstalled blender and got the zip file instead of the installer exe from the blender site and now have the folder,not sure why the installer version of blender didn’t.
Hi. I am having problem, the luxrender option wouldn’t even show in the addons tap at user preference. First of all, I am Sam, and it is a pleasure meeting you Jonathan. I have some questions, I have watched your tutorial and my question is, do I need to install first the luxrender 0.71 before doing the steps you showed on the tutorial in order to get it work? Again, I downloaded the luxblend 25 and put the luxrender folder in the script/addons folder in blender and it will not show the option on the addons user properties in blender? Please can you help me?
Thank you
Sam
how do I uv map
Add a image texture and set it to the Color channel. Also select that texture under the Diffuse setting for the material. The texture will automatically use the UV coordinates.
-Jonathan
Hahaha! I appreciate the effort but this has become rediculous. I’m no dummy and this thing took me 3 hours to get installed properly. I mean, what’s wrong with having an installer? lol And to be honest I got rid of the damn thing after about an hour! I used luxrender with 2.49 and liked it just fine. Especially, that nice button that approximated materials from Blender…Can you still do that? If so I MIGHT try again but I think I’ll wait til they get yafaray ported and hope its better, because so far the only thing more useless I’ve seen is POV ray. It takes alot to make me this negative. No offense to you guys at Cookie tho!
LuxRender is definitely not for everyone, the install process can be a bit challenging right now. Hopefully it will be greatly simplified in the near future.
-Jonathan
my guy keeps turning into a silhoute when I render what’s gone wrong.
Have you assigned a material to your model? If there’s no material it’ll likely show up solid black.
-Jonathan
thanks youve been really helpful
I have the same problem as stated in some of the previous comments. Running Blender 2.56 r34076 on Mac OS X 10.6.6. I downloaded the luxblend25-0.7.1.zip. Extracted its contents. Copied the luxblend folder to my blender/Contents/MacOS/2.56/scripts/addons/. I restarted Blender…in my User Preferences under Add-Ons, Render tab, Render: LuxRender is a dropdown item…but when I go to check the check box to enable it…I am unable to check it…..it simply will not enable. Any thoughts? Thanks.
-Andrew
Hey Andrew,
That version of LuxBlend is too old to work with 2.56 and newer builds now. Go ahead and grab the latest version from here: https://bitbucket.org/luxrender/luxblend25/downloads
If that doesn’t work it wouldn’t be a bad idea to try getting a latest build of Blender from Graphicall as well. While Blender 2.5x and LuxRender are both in heavy development it’s common to have to continue updating each of them so they play nice.
-Jonathan
Thanks for your help and everything youv’e done but lux isn’t for the things i want to use it for. can you suggest a fast free renderer that works with blender
Hey Jonathan!
Love ur toturials -
I’m trying to get this one to work for me.
My specs:
Mac OSx 10.6.6
3.06 Ghz Intel Core 12 Duo
4 GB Ram
Blender 2.56a
and Luxblend25 from the bitbucket link you posted above
I did the install of luxrender using the installer
I selected the 2nd option in this installer to install luxblend into the Blender folder
I opened packages on Blender app to verify that there was a luxrender folder in the addons folder.
The Problem:
I don’t see LuxRender as an option in my user preferences – anywhere…
any ideas?
thnx,
rich
Hi Rich,
I believe the problem is that you’re attempting to use the LuxBlend included with the installer. This is the old 2.49 version of LuxBlend. The 2.5 version must be installed manually into the /blender.app/Contents/MacOS/scripts/ folder. I would also recommend getting the latest SVN version of Blender from http://graphicall.org in order make sure API changes are causing problems with the script.
-Jonathan
Hey Jonanthan,
So I grabbed a fresh install from graphicall.org – ran the lux installer without the luxblend option and then manually added the files – and it worked!! Thank you!
Not the testing begins – I did run a render on a model I’m currently developing – I thought I selected “metal” as the texture but anyway here’s a screenshot:
http://motionshiftstudios.com/blended/pig.png
Blender kicked ff LuxRender but then shortly after, blender crashed – Lux has been running for about 13 hrs….
Interesting results – quite exciting! Thanks for all the help!
-r
PS: Where did you say Lux places the files?
Wow that was a fast reply! THnx I will give it a shot this afternoon.
-rich
Hey, Johnathan. I’ve got the same problem as Rich only I’ve quadruple checked that I’ve installed the 2.5 version of Luxblend and that I’ve put it in the Blender addons-folder. I also put the Luxblend_v0.7.1.py script that comes with the installer into the add-on’s folder.
I’ve even downloaded Blender 2.49 to see if I could access Luxblend in there but no such luck (opened blender – split the view – changed to scripts window – scrolled to render – found no options).
Here is the process I’ve gone through:
-went to luxrender site and downloaded 7.1
-Checked the luxblend python script selection in the installation process (the recommended one) and installed luxrender.
-downloaded the luxblend 2.5 file and copied the luxrender folder in src to the add-on folder of blender.app.
-started up blender, went to user pref, found no add on selection for luxblend.
I’ve deleted the files and restarted the process over and over again. I’ve followed your video very carefully and I still can’t figure it out. Any suggestions?
Hey, Johnathon, sorry for the double post. I just wanted to let you know that I got LuxRender to work in Blender 2.49b.
It’s a big step back for me because I have to model in 2.56 and then move everything to 2.49 and render in there because I can’t get used to the different layouts. If you can’t find out my problem with luxblend 2.5(or can’t be bothered) then I have a couple of questions:
-Are render times slower in 2.49 than 2.56 for LuxBlend?
-Will my scene get messed up when I move it from 2.56 to 2.49? For example, if I have a plane with a certain number of parent and child particles, will the values I have set (like the normal, random, texture settings, etc) get screwed up?
-Am I missing out on anything from anything major in LuxBlend 2.5 apart from the new GUI layout?
Anyways, thanks to anyone who may reply. I actually downloaded yafaray because I got fed up but then I couldn’t even get that to work :p.
So, here is my third post in a row – terribly sorry. I just wanted to let you know that I got luxrender to work in blender 2.56. Better yet, I’ve gotten SmallLuxGPU to work in blender 2.5. After spending the last three days at my computer trying to solve these problems, I came across this link:
http://www.luxrender.net/forum/viewtopic.php?f=30&t=4247
Download that and unzip it. After that, all your problems are solved. LuxBlend and SmallLuxGPU come bundled with the file so all you have to do is run blender and check the scrips in add-ons under user preferences. It was such as simple fix that I feel stupid spending so much time trying on this problem. Thankgod. I can’t afford octane and NVIDIA’s gelato doesn’t support mac, so this was my last choice. Hopefully, people with this problem can come across this post!
Hey, Jonathan, great tutorials i admire your time and im sorry to bother you but i cant get things to work as in your tutorial…
i use blender 2.56 lux render 0.7.1 luxblend 25 and i have a problem in texturing, under material i dont have T button for diffuse color and also missing uroughness n vroughness??? why is that? http://img195.imageshack.us/i/slikagt.jpg/
this thing is being pain in a neck for me over 3 days and it rely pisses me of
please help
Nemanja
Hi Nemanja,
I am not quite sure what the problem might be but my best guess is that it is a version discrepancy between Blender and LuxBlender. My suggestion would be to download the latest SVN build of Blender from Graphicall.org and the latest LuxBlend from http://www.luxrender.net/wiki/index.php?title=LuxBlend_2.5_installation_instructions
-Jonathan
thnx Jonathan, you are life savior it works!
Hey Jonanthan,
So how do you know when a render is done?
ALso, is Lux Render a good choice for organic materials? Like Skin?
thanks,
rich
I followed all the steps to the point where I am in User\nPreferences> Add-Ons> Render and I cannot tick the\nLuxRender box! It is there, But If I click the box to the right, it\nwont work! How can I overcome this problem? Please reply as soon as\nyou can, I Need to use this for a project!
This is really awesome
. I have a problem though. I can’t seem to locate my Blender Scripts file anywhere after about an hour of searching. I have version 2.56 beta, and am running windows 7. I was wondering (since this is apparently a common issue) if you may have an idea where they would be if not in the blender folder its self.
first things first.
thank dor your awesome tutorials!
then to the “broblem”
This is probably stupidest Quest in there… So i got it installed, found on add ons, cheked on, got all the options… But when i rend it all i got is black screen. u mentioned Pylux (what i don’t have) to render inside blender. however i see u have another application running named LUXRENDER. broblem is…
how to start up Luxrender “application” (where u watched rend results).?!? i mean no .exe files, or any start up files for such a application. i know somehow i must be very stupid for not knowing how to launch it.
Good morning Jonathon,
First off i would like to thank you for taking the time to post this video it was very helpful in getting Luxrender to work on my system. there are a few things though that i have questions about. First off i am very new to Blender and Luxrender and i recently created a simple rifle picture laying in the grass. once i got Luxrender to work i realized that it didn’t ever show up in the blender window or in the Luxrender program but it was being sent to the TMP folder so once i figured that out i clicked on the file and it came up in Luxrender and started to proses. However i have had it running now for close to 18 and one half hours it is still slightly blury as well as there is no color. am i doing something wrong? Or are there some settings that need to be applied to make things go quicker?
Hi Joel,
If you can send me your .blend file to test I can check it out. It is normal for LuxRender to take a long time but there may be some things you can do to speed it up.
-Jonathan
where would i send it to?
You can send it along with a run down of your problem to support@cgcookie.zendesk.com
-Jonathan
PLS Jonathan tell the reluslts u get with “joel’s” file i got exactly same problem!
no colours and mad render times.
don’t think there is anything wrong with files’s themselves, cos it does it, no matter wich scene i’m rendering with it. (No colours) only basic grey with shadows and render will take mindless times. Maybe stil some issues with installation.
i made “default screen” just added green material to the cube and rendered, but again just base grey and rendering taking about 5hours.under the “luxrender engine gonfirugation” at bar “LuxRender engine presets” only option shows just “luxrender missing paths”. Happens u have faced this problem or know how to fix?
For some reason I can’t enable the LuxRender Add-On…
Hi Kevin,

Hey there,
I also got a problem with Luxrender but i really want to get it work!
So here we go:
After installing Luxrender, i made a basic scene to test it.
I put a material on each object in the scene (chair,ground) and took a texture as diffiuse color, made a sun which shines inside the room through the window etc.
well, then i hit f12 and it worked..and worked..and worked.. and after one hour it looked like this :

And after two hours it looked like this:

No texture. And is it normal to render 20hours to get a normal render???
Hi there,
I believe the obscene render times is due to the window. If you want light shining through a window it’s import to use what’s called a “Portal.” You can read more about them here: http://www.luxrender.net/wiki/Portals

Okay, i´ll try that later, hope it works.
Another problem is, that as u can see on the picture, there is no texutre on the objects.. but as i allrdy said, i used a texutre as a diffiuse color like u did in the tutorial

Hello Jonathan!
. Anyother help would be much appreciated!!! 
I have just recently watched your tutorial on how to render a liquid filled glass in Luxrender but the only problem is that when I render the scene it only comes up with a completely black scene. The other night I tried to render a scene of some softbodies and it rendered just fine except all the color was gone. I dont know if its something in the settings or if I did something wrong when I installed it. Please help me as I have only been using Blender for 8 months now and am still a novice
Hi, I’m trying to use luxrender and i placed the luxrender thing in the scripts folder, BUT if I want to select it in the user preferences it shows it but I cant check it for some reason,, can you help me?
Hello,
I have an issue that my LuxRender inside of Blender(LuxRender console) does not show the rendered picture over time so therefor i can’t have the last rendered session saved, while in LuxRender GUI it works very fine, i don’t know if someone else have this problem too or i need to wait a lot more when using the console,but if there is a solution to it i would appreciate a help.
Thanks
