Stylised Outline Shader

Outline post process effect inspired by the work of https://twitter.com/harryh___h and https://www.instagram.com/drivemeawaytroubledheart/?hl=en.

A custom render pass is run to generate a texture encoding the outline information for each object. The render pass writes to the RGB channels of a rendertexture for outlines (R), inner detail (G), and noise that drives the line jitter (B). These values are used in a post process shader (also set up as a custom pass) to draw the lines by detecting color discontinuities.

I also set up a scene showcasing the effect. I used Photoshop and Houdini to make some models and textures.
