Toon Shader

[GrafOrlok]

Have you tried inkworks? I tried it once when I had the chance a year ago and it was pretty good. It featured a stand-alone renderer for doing the outlines. Whether this is a good solution or not I don't know, but the results where nice.

hoi, use cellShader v2.5 developed by Martin Leguizamon, a very fine toon renderer, many options, available at highend3d or at http://www.geocities.com/provide3d
cheers,

I've found that all the maya Toon shaders are limited in that they use the facing ratio technique. I haven't tried commercial ones for maya. I have seen what the toon shader in XSI can do through mental ray, and Nothing I've seen can even come close to that. Control on top of control. The guys over at Psyop use that and really know how to get in its ass. I would like to see a maya port of that shader but I have no Idea how or who would. Maybe someone out there will help...

is this a special XSI shader or a custom MR
shader - where i can see the shader working

[AWAKE]

I'm pretty sure its a default XSI thing. Theres a material and then there's the Lens shader - for the lines. so much control.. I got this off the Soft site

This is the one for the Ink

Check out www.psyop.tv They really did it right on the Volkswagen and the Lugz, and they were using these shaders.

What about the new rampshader in 4.5?

[alphatron]

The ramp shader works fabulous for everything BUT good ink outlines.

what about the displacement method? there are various tutes on the web about it (includingo n my site) for the various apps, i'm sure it wouldn't be difficult to transfer it over to maya. all you really need to do is map an outline colour to a duplicate of your object using a decal shader mapping it to the back faces (the front faces need a transparent material) and then giving the whole thing an even (or uneven if you want a more uneven line) displacement of however wide you want your line to be.

[Per-Anders]

oh and then for the actual surface material of the original object you would probably want to remap the luminosity ( i think that the surface sample node isn't it?) into a gradient and flatten the whole thing off into whatever steps you need... although isn't there a simple posterize shader inbuilt somewhere in maya?

[AWAKE]

Never heard of the displacement method. Where is the Tutorial? It sounds real interesting. Especially for the rough stuff. Usually I get the outlines in the comp, but roughening them so they work in 3d is a little tough. (I'm no tablet jockey) Where where where is this magic tutorial?

[playmesumch00ns]

You can't get outlines in shader, cos the only way is to use the facing ratio technique, which is crap basically. You need a render plug-in

Inkworks is pretty good. I'm currently in the process of writing my own but maya API is a bastard at the moment and nothing bloody works!

Choons,


Develop develop develop..... Id love to see something deeper than mel for a maya toon shader.

There are many out there.
Of course, you have to pay for them ... :p

oh yeah....

"Final Toon Shader" at highend3d.com is good at generating lines, even on planar surfaces, though the actual quality of the lines is not so great (they are a bit grainy, but look ok if scaled down later).

[Per-Anders]

awake... check out the renderzone section of my website

http://www.peranders.com/c4d8/

then in the tips section there's a toon shading tute (using the displacement method)... i'm sure it oculd be translated into maya no probs.

[beaker]

The XMB Cartoon Tool Set is pretty good. It uses a post process tracer to get the outline.

You can dowload it here at the bottom of the page:

Awake > edge-detection and toon-shading (well, i'll just leave it up to a ramp shader probably, tho may write my own version for the 4.0 release) is actually the first thing I'll be doing as part of my NPR plugin for maya, provisionally entitled NPR Effects, or maybe NPRboy (was going to be NPRMan, but I thought that would be too cheeky).

Actually if anyone can think of a better name, I'd be most appreciative!

I hope to have a working version going by xmas (fingers-crossed) for download and beta-testing (well, alpha really), although it will most likely only work on polygons, and you will certainly need a graphics card that supports at least OpenGL 1.2. but then, that shouldn't be a problem
