The cycles shader toon seems to do exactly what I want, it's different from the other toon shader. (but youd still need a B&W color map for the face,) Also the ccyles shaders seem to only work in the Superfly renderer which seems to have global illumination going on so you need a scene thats black for black shadows?

Unfortunately the cycles shaders are porrly documented.

I am still surprised there is no input to this thread, there must be s.o who understands the shaders.

Cause now I am interested in how people do these watercolor shaders, and I have no clue and no material example. Does anybody have an example? Does that inly work in the pro version?
