Your first Volumetric Fog Shader | Unity URP

A gentle introduction into creating a volumetric fog shader from scratch, explaining the overall logic behind volume raymarching. There's a lot this video doesn't cover but it should serve as a good entry point for game developers and artists that seek to understand volumetric effects.
