UE Toon Post process material. Originally I made it a few years ago for some personal project and it was built around the concept of creating decolored lighting mask from postprocess pass to use as the etching mask. in shaded areas. It was way easier to do without realtime GI, but I was wondering can I make some practical and plausible looking toon effect to use with the Lumen, and well- Yes ))
In addition to the etching lines, I added custom lighting inside the post process for specular banding and some other things, like blueprint style rendering and tonal and color controls for lights and shadows.
I will make free to download scene available later.
