1. Research

Unfortunately, I didn’t find any sketch shader tutorial online.

2. shader Test

Zhan gave me his shader to play around with, but I found those inner lines would move as the camera moves, so I decided to find another way to achieve this effect.

So he suggested me find some sketch textures to add them together.

Lexi made Pinwell’s room and applied sketch shader, this is how it looks like.

3. Shader for Pinwell walking

I can get different effects by changing sketch textures and tweaking parameters.
