Using Multiple Textures on a Single Entity

[MrBigzy]

Even if a game supported multiple textures, it's not good practice (except maybe for some sorts of complex animated textures).

Models seem to have separate textures because they are distinguished by UV's. For these models, the texture itself is one photo with a bunch of different textures lined up against each other. The UV coordinates are used to tell the model where the texture goes on specific parts of the model, and which part of the photo the model will use for that part.
