Hehe ill tell you now that its only a quick fix
. I know exactly what I did wrong in the beginning now; I assumed that the texture associations of parent nodes applied universally to their children; which I had no reason to really. I've hooked up textures quoting the correct .tga to the barrels as well as the turret housing so the guns should look fine, but the textures aren't exactly the same as they should be - you'll never notice the difference. When I release the next version I'll remake the guns with all the stock texture nodes but for now the guns will still look and act fine with mine.
