[Tutorial] Full Screen Shaders (Custom Post Processing) in all 3 renderers

This tutorial covers how to run a shader against your rendered scene. Sometimes called full screen shaders, sometimes called custom post processing effects.

HDRP uses the post processing stack, URP uses a custom renderer feature, and the built in pipeline uses a MonoBehaviour callback. All that to say, it can be a bit tricky to keep up with. So I've made a one-stop shop to get you set up regardless of renderer.

this simple example makes a small section of the screen full color, while the rest is black and white.
