.MAT textures

[Pingus!]

I was trying to extract models from the game Star Wars: DroidWorks, and the textures are in the .MAT format. The game uses the Sith engine, and the models and textures are the same format as the game Star Ware: Jedi Knight - Dark Forces II.

The resulting BMPs look like this:



How do I get the clear texture? The tools can be found here:

Wild guess, but is the alpha channel possibly on in this image? I probably have no clue what I'm saying, but that's what I think the issue is?
