what's a good program to use to work on RGB layers and the alpha layer separately? i've been able to get flashing emission maps to work just fine with the tutorial, but exporting an image with a black alpha layer in GIMP to get a permanent light has only yielded transparent images without any of the RGB data. would this also be because i exported them as png instead of dds?
I'm responding to an old post, I know, but yes, you need to use a DDS file. A PNG file won't support an alpha channel.
