In this tutorial video , I show how to use the Custom node in the Unreal Material Editor and the Custom Function node in Unity's Shader Graph to add HLSL code to your graph. You may want to do this to reduce the amount of spaghetti in your graph, to use existing code functions, or to get around the limitations of node-based shader creation. Writing shaders in HLSL is a very deep topic and I only just scratch the surface here.

Here's the code we used in this video:
