Thats good, but I think it's Raven's screwup that needs to be corrected. It's always been my experience that glow channels inside a TGA are greyscale, with white the most opaque and black the most transparent. So it seems to me, for it to be done right, the glows have to stay on the Diff and the extra map needs to be greyscale. That should make it easier for you to make a mask from the glow map, add it as an alpha channel to the BMP and save it as a TGA.
The glows on the model are better, but they are still not bright enough. If you know of some way I can fix that on my end, or have someone here do it, let me know.
