[Maya] Hand drawn shader/render ?

sawcisson

Hi just passed by a short film and i'm really intrigued on the way they did those environment , is it texture? is it shader? how could i do such thing ?



i found this article about this short and it seem that it used some 2D filters to generate that water colour etc... on the video

But i'm still a beginner and i can't understadn exactly where to look and how to achieve it.

Here is also a breakdown video : 

what i can't figure out during that breakdown is if the drawing are generated or if they are texture .

It looks like textures combined with a very fine extrusion and flipped normals to me!

An opinion on the piece:
Very nice textures, good lighting and design! Shame the animation itself is a little bit janky. Haven't watched with audio and only flicked through though

sawcisson

Yeah the characters and animation are not really great but the environment is very great.

EDIT: I also found a breakdown but don't really understand the real way they do it

You should sculpt or generate a procedural tileable rock normal map that you composite in Blender Compositor or Substance Designer (Maya can't composite an image) then you project the texture as box mapping. The node setup in Blender:



You can overlay it with a curvature smooth map to get more color variation on your texture:



You can quickly get lines based on the camera angle with a fresnel node used as a factor with an emissive shader. A color ramp set in Constant mode allow to control the thickness:

So much informations ! so i should work with another software to do that kind of result hum i don't know how hard it would be to learn those things

poopipe

you can set that shader effect up in maya using a ramp in conjunction with a samplerinfo node

MrBFox

not sure what version of maya your using but theres also the Toon-line and two-tone shaders, but if not the samplerinfo method Poopipe mentioned is also handy.

i use 2018 , but i can't find a way to make the toon-line etc... working with arnold or maybe i'm using the wrong render ?

oglu

arnold does not have a toon shader.. but one is in development...

you could try to work with the facing ratio...

Hum , but in maya 2018 there isn't any other render system than arnold if i'm not wrong ?
So all the maya toon effects are useless ?
Sorry really not used to maya rendering
