Its a great thing. all u have to do is export ur scene as Wavefront (.obj)
and load that file it Uvmapper. Then go to edit and select new uvmap, just select the shape of the map and tweak some settings and Viola! a great uv map with no complicated crap
Edit: Srry Admin wrong forum.
EDIT2: Im not sure now how it works and if it does ill keep testing and reply later :-?
