Soo... just wondering... wouldn't you have to change it back to .tga, add alpha channel back (since warcraft skins must have an alpha channel, to my knowledge)? If so, than you'd have to reskin overtop of some black areas where tema color used to be, and then, also, aren't some of those areas un-skinnable?
On some units and areas, its easier just to go into the alpha channel and remove the team color that way ://// |
