Outlines on One Object in Unity URP Shader Graph with Edge Detection! ✔️ 2020.3 | Game Dev Tutorial

✔️ Works in 2020.1 ➕ 2020.2 ➕ 2020.3 🩹 Fixes:
► At line 39 in OutlinesInclude.hlsl, the sixth entry in sobelSamplePoints should be float2(1, 0), not float2(1, 1)

Outlines are a great way to add polish and style to a variety of games! In this tutorial, I apply depth and normal outlines to single objects, allowing different outline colors. This technique also skips the post processing step, which can be a big performance boost for lightweight platforms!
