In this Blender 2.5 video tutorial we show you a technique that makes use of array and curve modifiers to create light streaks like those you would see froma long exposure capture. The tutorial covers modifiers, materials and node compositing.
Note: this tutorial uses the official Blender 2.5 Alpha 2 release.















Hi, Reyn here. I think you got the wrong description for this vid tut.
Quoted: “In this Blender 2.5 video tutorial we look into how to UV unwrap a full, stylized female character. The tutorial covers creating seams, unwrapping, pinning, and techniques to reduce stretching.”
Hope this helps. Cheers.

Ah, fixed

Nice!
I always wanted to do this in blender. but never found a easy way. Thanks, and good Job, Johnatan.
Fun. Hey, I noticed that about 1/3 of the way through the video you selected some points on the curve . . . but it wasn’t a box select more like a radius select or something like that–how did you do that?
@Will: that sounds like pressing “b” twice. Then you can “brush select” and modify the radius with the mouse wheel
Great tutorial! More of that stuff, please!
@Corniger, @Will, the circle select is actually done by hitting “C” in Blender 2.5. In 2.49 it was “B” twice.
Is there a way to make it so after like 3 seconds it will fade?
I dont know if I was too clear there :\
more like http://www.youtube.com/watch?v=BY0YBhnAevU
You could make it fade by adding a Start Cap to the Array, giving it a blend like the End Cap, and then rather than extending the array along the entire curve you could send it part way and then move the actual arrayed object, causing it slide along the curve.
I’ll try that out, thanks!
Jonathan all your tuts are awesome and I find them very easy to follow… this site is one of the reasons I’m thinking of finally getting a paypal account.
@Will that was Ctrl-LMB holding control to draw around them
@Corniger I think your refering to “c” circle select.
actually, in 2.5 it’s “C”
Hey Great tutorial, This is something i can use.
@ Will and Corniger btw, in 2.5 to “brush select” you can use “C” instead of “B” twice in previous versions.
@Will and @Corniger
I thinks it is actually the lasso select. Hold down “control.”
That’s what I’m looking for. Thanks.
Will
@Will and @Corniger and @Tim – yes, he was using lasso select, hold Ctrl while left-click and dragging
@Jonathan – mind=blown. nice one.
@everyone,
Thanks for the help . . . of course, the lasso select has been around since at least 2.49. Doh! You think you know a program . . .
You would be much better off and have a lot smoother results using add>curve>path.
It’s easier to make smooth paths with just a few points, it behaves similar to using nurb handles.
This reduces a lot of steps… (no converting to path, removing points, refining curve.. etc) if you what more resolution just up it in the curve options panel.
thanks for another great one, Jonathan.
Until now, you have the best 2.5 tutorial videos out there
Very nice tutorial! Thank you Jonathan ! I particularly liked the “Node Editor” part (actually first time i used it !!!). Let’s do some light painting in Blender now
!
Great tutorial, Thank you very much Jonathan.
Only one think, to use Select Every Nth you should select only one vertex before.
I realized that’s probably how it worked immediately after recording, thanks!
This is awsome. Never thought of using an array like that. Like you said, particles are just too messy most of the time. They are more suited to things like fireworks or explosions.
Nice tut once again.
Just one thing:
You can save time cleaning up those curves by increasing the manhattan and cerulean distance settings on the editing tab under user preferences:
Using big values (>30) lets you easily block out the overall shape (at the cost of losing details).
To get rid of the blocky shape after doing this change the paths spline type to bezier or nurbs, whichever you like.
Great tutorial as always. Thank you!
Very familiar to what Otavio Tatasoka did http://www.vimeo.com/2330279
Thanks for sharing!
Great tut btw, nice effect.
THis is so freakin cool! How do you suppose I could animate it so that it retracts from the start point as it goes along?
Also, there’s forums for blender cookie?
Jonathan, is this the answer to the Force lightning I wanted? How do I make it crackle?
But this is really cool, I’m not that good at 2.49, and so 2.5 is totally new.

Cool tips as usual, nice tutorial…
However, I think I followed it carefully but still have a problem with unwanted lines displayed in the rendered streak (with or without textures applied).. (I suppose it’s related to the modifiers ? I’m lost..)
Here is the picture :

And here is the .blend file
http://hostit.warrenberberd.org/dl.php?file=cd7517ddb2145b49215169844b802292
Any clue about this ?
Is there any way to easily flip all the streak mesh towards the camera
(because every time the mesh is flipped away from the cam the graphics go bad)?
The longer the streak is, the more tedious work i got until its all finished.
thanks for your help.

@jonathan: keep up the fabulous work youre doing

Hey, nice tutorial. I was wondering if you could help me with something else though, Blender keeps crashing on my computer and I can’t fix it. I heard about the bug in this tutorial and was wondering how I could fix that. I’ve tried re-downloading 2.5 alpha 1, as well as Alpha 2, as both are experiencing the same type of problem. I hope you have an answer, because everything I’ve made in 2.5 so far can’t be opened by it now.
What can i do to set the start point to the other end of the curve?
While in Edit Mode for the curve press W > Reverse Direction

Thanks Jono!! that was awesome!
@ Matthew: I believe he just changed to top view by pushing 7 on the numpad and then split the views?
i cant watch it
there stands
this is a vimeo plus feature
This looks like it was a Vimeo wide bug for some reason, but should be good now. If not drop us a note to support@cgcookie.zendesk.com and we will help you out.

hey great job do a tut on modeling a airplane or tank
Great Tutorial!
But I actually have a problem. I want to put these streaks in another project where other things are in, too. But if I do, my Nodes don’t work correctly because they apply to the whole scene!
How can I seperate my streaks from the rest for the nodes?
Thanks in before,
Ivorius
Awesome, I’ve been looking for a way to do this.
Thanks, Jonathan!
