Every separate piece of texture creates new surface, and every new object (and it's textures) does this too.
Since objects need to be separate for culling and game purposes (like characters, props, level parts) they should be textured like that, meaning that character should have it's own texturemap and gun it's own.
You could combine even those, but since they are separate objetcs there's no point really to do that. And so on...
