ok, i'm still having issues, turns out that was the same importer that I used. I am using Umodel to get the the .pskx files, i don't know if that makes a difference. On some objects with multiples groups, like trees, cars, or walls for example, Blender will only read one of the groups' UV maps, and the rest it will jam into one vertex in the corner of the map. are there any specific settings you've used to prevent that?
