Decals in URP & HDRP #Shorts

Full Tutorial: https://youtu.be/5p8cKIu3P_8

New in 2021! URP (URP12) supports a Decal Projector much like HDRP has had since HDRP6!

Many of us who aren't super comfortable writing our own shaders relied on 3rd party tools for decal projections or went with simple quads for decals. As of Unity 2021, URP now has a Decal Projector much like HDRP has had for a while. It's not perfect, but it's a big improvement over the quad-based decal systems I've implemented before. I'm hopeful the URP one continues to get improvements as new URP and Unity releases come out.

In this tutorial I'll show how to enable decals in URP, review all the configuration options in the render asset and what they do, and go over what all the decal projector options do. We'll do the same again for HDRP so you have an informed starting point for adding decals into your game regardless if you're using URP or HDRP.

Unfortunately the Built-in render pipeline still doesn't support them without custom shaders, so you'll have to write your own or use a 3rd party solution to get a similar result over there.
