How to add textures to a material?

I’m trying to make it so that a material has a texture on top of it, so not using an image as a material but sort of combining the two? I don’t know if that’s possible but that’s the best way I can think of to describe it.

Right now my goal is to make it so this golden material I have can have a symbol on top, I tried googling regarding textures and stuff the only thing the manual says it to “assign the texture to the material” but I can’t find anything about how to do that and the only tutorials I could find are from over 5 years ago. So, how exactly do I assign a texture to a material?

Depends on the material, but usually you just make a material asset, select it, assign the texture via its inspector. 99% of materials will have a main texture input. There’s not much more to it than that.

Each of the render pipelines will have slightly different inspectors. Refer to the docs for the rendering pipeline you’re using.
