Objects with more than one texture

[WALP]

are you familiar with the term UV mapping? or are you talking about the textures location on the pc?

I'm not talking about the location. That should be something fairly minor.

UV mapping is when you lay the object out in 2D right? I've seen some people texture using that, but how does it work with that .dds? They took a snapshot and fixed with GIMP 2.

It works with a .dds just like with any other texture.
To fix the stretch and stuff you need to UV unwrap it properly.
UV mapping is essential for almost any model in any 3dsoftware so there should be plenty of tutorials for you to find out there.
