We also need to download the image you used to texture it, if you look at other units textures, you see them cut up, each piece goes to this spot, yada yada, we need a image to draw over, then we can test it in game. and once we are satisfied, we can give it back to you to do whatever with :]
so, we will need to at least download your current texture your using, and if you would like us to test it, see how it looks before giving the texture to you (to make sure there are no glitches, blank spots, you know...) then we would need to download the model also.
