Hello what i do is this.. First modle the props as an individual piece, so if you have 2 pieces,export them from your modeling prog as obj. Then run them in uv mapper and save the maps and the obj, then import each piece to poser position them were you want them and them export as one obj,then bring them back intop poser and there you have one obj with both groups and materials set up so all you do is paint on the maps and apply them to the prop hoipe this helps regards seeklight
