Displacing displacements for curly paper

Recommended Posts

I have been playing around with a displacement shader that is supposed to make polygons look curly (see picture 1 and HIP file).

Would anyone know how to make them actually peel off so they dont fully cover their initial surface (picture 2)?

I think Kai Stavginski mentioned in his shading masterclass that its possible to displace displacements in shaders..

Yes, when he was talking about cracks he mentioned that he can displace within displacements. He did not show how to do it, though.

I have looked at your file and tried to create a valid Normal input for your Displace Along Normal node : the idea is to mix between the normal of your face when s is around 0.5, and normalized (P + dPds) when s is close to 0, and minus that when s is close to 1. This should shrink the face in the direction it is bending as you want.

I will share the file once I have tried (it almost works, but I have to make an if statement to reverse P+dPds once s>=0.5.... but it already reduce the face
