I made some procedural shaders but didn’t know it would look similar to your filter.
So I voluntarily helped a person with a project and here is the first test render: https://youtu.be/oAs9jOX_IEA
There was only one of my materials was used in that test, and I haven’t receive any message from the person for a while.
Here is the first one, the ground shader: ground.blend (939.4 KB)
The second one is a wall and ceiling shader: wall.blend (616.1 KB)
The third one is an EEVEE stylized PBR shadow: shadow and cube.blend (926.3 KB)
The cube’s material is an example of mixing the effects.
The fourth one is an EEVEE stylized PBR glass shader: Glass.blend (738.2 KB)
The last one is a fishbone (chevron) shader: fishbone.blend (745.6 KB)
I made it for a duvet in a scene. I don’t have the image of the scene, but the idea is making the sleeper under it look like a dead fish.
