I've done gloss maps based on this thread (http://www.twcenter.net/forums/showt...gloss+tutorial)

Now, in the end I need a dds.tga file and a tga file. I get what the first one does, but Im not sure about the second file. Right now I've saved a version of that file for every unit that Ive made gloss maps for. But do I really need it for every unit, or on the contrary will only one of these files (with only the faction name in the file name) be enough to work for all units in that faction roster?
