I'm trying to make a simple 3D house with doors, roof, and stairs, I made all of it from the same cube so it would all line up perfectly-ish.
My trouble is I have no idea how to remove sections of it from the block so I can set the material and textures how I'd like.
So for instance, I want to make the doors out of wood, and not have the entire house look like a door.
Thank you.
