If you're wanting a program strictlly for uvmapping purposes, then uvmapper is deffinatelly the way to go...low resource usage, and just as powerful if not moreso than the high end aps... If you're bound and determined to uvmap with something other than uvmapper, I seem to recall mallen telling me that body paint does not change the obj or maybe it does, but there is a simple work around...can't remember for sure... my suggestion is to stick with the program you know and love for uvmapping, and use those others for what they were origionally intended...texture creation only... The only other program I've heard of but not much about is the one daz uses, its called Flesh, not sure how it treats the obj files, but its another to look at if you're bound and determined to spend some money hehe
