Gooch shading on NME

Yesterday I saw a video about an interesting non-realistic shading technique: Gooch shading.
What Is ๐“–๐“ธ๐“ธ๐“ฌ๐“ฑ Shading? - YouTube

It is based on this short paper: and shows a lighting model that contrast warm and cool tones inspired in technical drawings. So I wanted to reproduce it on NME :smiley: Babylon.js Node Material Editor (

Itโ€™s just missing the outline part, as I havenโ€™t figured out a purely NME solution to my satisfaction, but Iโ€™ll leave this for later. :slight_smile: Feel free to use and modify this as you wish!

Have a nice day everyone,
