Unity Shader Graph Basics (Part 10 - Custom Functions)

Unity only provides a Main Light Direction node for custom lighting. If we want more fine-tuned control and support for color and additional lights, we'll need to delve into the world of ✨custom HLSL code✨. With Shader Graph's Custom Function node, we unlock plenty of new opportunities!

I'm using Unity 2022.3.0f1, although these steps should look similar in previous and subsequent Unity versions.
