Since the “Shader to RGB” - Node only works in eevee…
What would be the best way to recreate something similiar in cycles?
From the web:
There isn’t a shader equivalent to that in Cycles, mainly because in raytraced renderers like Cycles, each object impacts each other in the scene (while in raster engines like Eevee each of them are basically independent). It’s not technically impossible if the devs wanted, but it wouldn’t be efficient. You can bake your shader into textures and then redo a shader with these, or edit your shader in compositing.
There is no direct node that does the same thing. For cel or toon shading type work in cycles there is the toon shader. There are topology and complex node setups that can be done, but nothing as easy as the Shader to RGB. Although with the new light linking in 4.0 you can achieve better cel shading in cycles with less node work or at least that’s what I’ve read. I haven’t played with light linking yet.
