C# Scripting With Materials in Unity

This video explains how you can use C# code to edit and set properties on materials in your Unity projects. We cover the difference between editing material instance vs the material asset itself, we show you how to find the names of Texture Maps in the shader definition so that you can edit them, and we explain how alpha and transparency works in Colors. We are using the Universal Render Pipeline materials for this video.
