Troubles with SurfaceTool and textures

Hello everyone what I’m trying to do is some procedurally generate a plane and place a texture on it. I have the plane generating and I can put a material on it, I just for the life of me cant figure out how to put a texture on the material so that it shows the texture. I guess I should also put this here… Once I get this working, my plane will have tiles with each tile being able to have a separate texture. Are my uvs setup for that and how would I go about doing that?

I am using C# btw. But gdscript answers are welcome since its fairly easy to convert between them. Thanks :slight_smile:
