In part 2 of this Blender 2.5 video tutorial on creating a CG Cookie branded coffee cup we go through the texturing, lighting and rendering process. Techniques covered include creating a drop-cloth background, creating easy-to-control duplicates, procedural textures, and rendering depth-of-field with the node compositor.

very good THX JONATHAN
Can someone help?
I’m trying to follow part 1 of the coffee cup tut and the part when you extrude the top for the rolled lip, I can not for the life of me get it to select the top loop, it only selects the individual vertices or sections….it will no select the only the top loop/vertices. What am I doing wrong. I’m trying to right clik the top loop while holding shift…is this right? Sorry, I am a complete noob and appreciate any help that I can get.
Thanks in advance.
PS…you guys have great site here and I appreciate all the helpful info.
you have to alt click not shift click. (im a little pissed off that everybody just skipped your comment and ddnt help you.)
We do our best to answer all comments directly asking for help but sometimes (particularly on weekends) we are a bit slow to respond and may not get to it until the next day. Thank you for your concern though

Like snee said, you have to ALT + Right Click to select a loop. If you ALT + SHIFT + Right Click then you can select multiple loops.
Good luck!
-Jonathan
@snee; no worries!
Thanks…I listened to that part about ten times and never picked up “ALT”. lol I had my kids running around the house being crazy too, that probably didn’t help.
Hah!!!, now I know why my decals never work right. Great job.
Great tutorial,thank you
Thanks. That was a great tutorial. I’ve learned so many new things I’ll be able to use in my work.
Great tutorial! I learned a lot.
Did you stop the recording at 2:58 to stop the noise in the background?
As a matter of fact I did. My dog decided it would be a good idea to go tearing through the house with a bone and then drop it at my feet
also stopped in 5:11 ^^
Hey Jonathan Thanx!
The Texutring part is difficult to understand, because you cant see the uv-mapping changes immediatly in the viewport!
In C4D evrey change you made in the mapping settings, you see it live in the 3D viewport!
Nice tutorial. But why did you need to set the normal factor to -2.0? My understanding was that 50% gray has no effect, light gray has an additive effect, and dark gray has a subtractive effect. So since your image for the lid was 50% gray with black details, wouldn’t the texture already be making a dent in the lid? It seems to me that setting the normal factor to -2.0 would invert the image and have the effect of creating ridges coming out of the lid.
Love it! Though I could use a hand, I lost my lid. D:
I’m at about 11:54 in the movie, where we’re adding the logo to the sleeve. And, I think I hit something which hid my lid in rendering, and I can’t for the life of me figure out what I did. Can anyone determine what I might have done by looking at my current display?
It’s not hidden – as you can see it’s seen in my 3d view, and everything is on the same layer.

Thank you!!
You may have turned it unrenderable. Check the outliner?
That was it! Thanks!
Now I know how to use the outliner as well, haha.
Jonathan Williamson, You’re my hero man! thanks to you I have a couple of tutorials, and you are pretty simple with the controls and stuff… in my first week of blendering you are helping this poor noob to go somewhere xD
I’m cracking head with part one right now, I just can’t get the perimeter edges right, they keep weird (18:30 – 18:50) but I think I’m selecting the wrong vertices….
Can’t wait for me get the model done and go to part 2

Awesome… it’s great seeing texturing techniques… I’m a fan of subtle DOF also, in conjunction with the compositor. You ever use PSD files for your image textures? Just curious if it’s better practice or you get better results to use PNG’s instead. Anyway, thanks for the tutorial and keep up the great work!
I use PSDs from time to time but I have found in 2.5 they seem to stop working sporadically. PNGs are more reliable I have found.
…a wealth of useful knowledge covering a variety of 3D modeling/texturing/lighting topics that would perhaps require,otherwise, a whole book to be presented!…your tutorials are no doubt the best around ( as well as those by Dave Ward and Kernon Dylan not to forget!…)
…once more,thank you guys for sharing your knowledge with the rest of us in such a a great way…IMHO you’re offering great services to the community!…
OK, I’m stuck again…next step after my last post…when I alt/right click to select the loops to I can expand the lip out over the top edge, I can’t select sections, it will only only select the top loop and bottom loops with the vertical faces not connecting them to form entire shaded sections.
I’m going to start over and see if I skipped over something….ADD is a b!tch.
This sounds like you have some duplicate vertices. This can happen easily if you extrude but do not move the vertices. Something to remember, is that wen you right click to cancel the transform it ONLY cancels the movement, not the actual extrusion. To solve this just go ahead and select everything press W > Remove Doubles.
-Jonathan
Makes sense…I think that is what I had done. Now I have a couple other basics to get sorted that have me stuck.
What a steep learning curve! and I thought P90X was hard
Thanks for the feed back
OK, still I would like to know why…but, after starting over, everything is going smoother now. This is starting to remind me of when I started Photoshop.
I completed the two tutorials.
I lost track of how many hours….errrr…days it took me!
I went from almost zero Blender modeling knowledge to feeling like a talented amateur now.
One thing that puzzled me for awhile, I don’t think you mentioned it, was that the java jacket edge from the Solidify modifier looked terrible. It had some dark parts that I couldn’t figure out how to remove. That is until I applied the Solidify modifier. Then the java jacket edges looked properly textured.
Great tutorial.
Keep em coming, and thanks for mentioning every keystroke you use. It’s impossible to follow if you don’t do that.
Thanks.
LOL…I’m with ya. I still haven’t finished it yet…I can’t quite get it to “do” everything like in the tut. I always have some kind of issue. Hopefully I can finish it soon. I think I’ve started over about 25-30 times.
I do have a question about the backdrop.
I can’t seem to get rid of the banding between the light and dark parts of the backdrop.
I tried increasing the “Samples” under Gather on the World tab, but that didn’t solve the problem.
Is there some way to fully get rid of the banding?
Thanks
Yay, finally it’s finished
Well done!
Just one thought: wouldn’t you have way more controll if you used an empty as your focus point?
Cool tutorial ! My result : http://img196.imageshack.us/img196/5779/0002wd.png
Hey that looks great!I would love to see you take it a step further and add some coffee inside of the cup so it actually looks like it’s spilling out. You could combine the texture on the ground with a simple fluid sim.
-Jonathan
Thank you,
I will send the result with the simulation when I finish.
No one had any ideas about my backdrop banding question?
Could someone please lend a hand on how to completely eliminated the banding I see in the backdrop, especially as the backdrop gets gradually darker. It kind of a give away that the image is fake, or at least compressed. I tried saving both as a png and uncompressed bitmap. The banding was there with both. It’s subtle, but it is there. Is there something in the render settings or raytrace settings to eliminate that?
Help?
Great tutorial Jonathan. Watching made me miss working in Blender. You guys should think about doing a tutorial on how to use Blender on a Mac. There are really no good tutorials out there on the subject.
Assuming you have a three-button mouse everything should be the same. Is there a particular problem you are running into?
-Jonathan
I didn’t know about the object mapping. That will come in handy for a little project of mine XD
Great tutorial!
The Source File Download isn’t working…
An excellent tuto, thank you very much!

I just finished the tutorial. Well done and I leaned a lot of tips.
I had two problems. First, I accidentally dropped number of vertexes of the circle for the lid to 11 which really screwed things up later. Still, it turned out OK, but not as good as I would have liked.
The second problem is still a head scratcher.
When I map the empty with a logo on the Java Jacket, it looks great from the front. But when I tracked the camera around the cup to check the sides and back, I see that the logo is on the back of the Java Jacket as well only reversed as if looking out of a restaurant window and seeing the sign backwards.
I wouldn’t mind if all I was going to do was to render a picture from that one angle, but I was including additional recycling images normally found on hot cup jackets and so all the images are displaying twice front and back.
Is there a way to limit the empty to the front of the object without it displaying in revers on the back?
I’ve tried UV, but the results are not as good.
In a related question, I wanted to include repeating text along the bottom of the jacket as you sometimes find such as the company name.
However when I repeat the image, it repeats in both the X axis and the Y axis. Is there a way to repeat an image in the X axis only using the “repeat” option in image mapping? It seems logical that I should be able to set the Y axis to zero, but “1″ is the lowest it will go.
Any advice would be appreciated.
Thanks,
