Pencil Sketch Renderer

Hey guys.

I need a renderer for Maya 7 to render animations that look like hand drawn pencil animations.
Tomcat Cartoon Shader would be an example, but I found only a version for 6.5

Can you recommend me something?

Here's an example:
Something between the bottom left and the bottom right picture

Bottom right and left picture are awsome. I think U can create this images with ability of paint effects and toon tools in maya 7. There is a lot of brushes & options U can tweak.

In deed they really are awesome.
I tried it out on Maya 6.5. The bottom left picture was absolutely no problem to make. There are some MEL files with presets. The bottom right picture requires some special settings which I was not able to find. Unfortunately I didnt find any tutorials for this great (free!) plugin. Additionally the website disappeared and theres no more support for it. Bad luck.
Maybe someone could give me a hint, where to find some instructions for it.

I also tried it with the paint effects and toon tools in Maya 7. They work good, but not as good as the mentioned plugin. I was able to create toon looking renders but none of them looked like "hand-drawn" like the to bottom pictures. But maybe here again it's just a question of the right settings. But without some help I'm not able to make this right. :(

By the way, what's the name of that plugin, You're talking about. Any idea where can we download it?

As I wrote in the first posting: Tomcat Cartoon Shader.
It became freeware. But its website is not available anymore.

I uploaded it here for all those who are interessted in it:

If you find out how to create renderings like the last one, please post.

all renderings you posted are pretty basic in maya, except the bottom right one I think.
I think they are even in the maya's presets [tomcat toonshader is the base/essence of maya toon renderer now]
even the bottom right one may be the pencilShading.ma preset just noticed.
try to do some tweaking and you may get nice results.
I don't have any experience with toon render in maya, so my help is pure theoretical, hope you won't mind.

pencilShading.ma rellay seams to do a similar fine job.
one problem is that the created pencil strokes are created from a static noise layer. i would need something dynamic. otherwise it doesn't look handdrawn. because all strokes stay where they are, nevertheless if the scene is rotating or moving. (like a projection from the camera)

i see two possible solutions for that:
1. change the offset of the noise for every frame.
2. use an own short animation instead of the noise layer.

unfortunately I don't have skills for both of the solutions.
the first one might be done by using mel. (how can someone give an example for changing an offset dynamically in every frame?)
for the second i would need an animated texture. never used one before and i have absolutely no idea where to set this up. :(

well, I am not a mel expert, but for a start find which attribute/s in shader when changed does the job for you, and then think how to animate them.
the simpliest way is to right-click on attr.name and set key, then go ahead 12 frames change the value and set key again...
but first find the attributes
good luck.

Well, I guess that it is a good idea to start one thread related to toon rendering in Maya, in order to exchange experience and dicover interesting techniques. This is pretty unexplored area in Maya.
 
  03 March 2006
good start would be to explore help a bit. there are plenty of useful info for beginners.
also you can find some good stuff here:

this is really cool.




derived from the expression code for the shape i made this code for the moving texture.
looks really great.
though i wasn't able yet to create such a outline as in the above picture, but i'm working on it.
if you find more such great links please post them.

float $val = rand(0, 1);
  setAttr ("noise1.randomness") $val;

heh, everyday I learn something new...
I was covinced that my theory is right, but guess I it wasn't...
sorry for confusion, if there was any...
