   Palette Swapping a texture
  Can you do a palette swap on a texture?You know how in a game like Warcraft III, each side gets the same units, but with different colors. How is that done? I doubt they have multiple versions of the same texture, that seems to wastefull to me.Any suggestions?   
Here is a thread on palette swapping started a week or two ago.  It's short, but it provides an answer or two.
