heyas; they have a big expensive mapping proggie ;) but you can do something farily simple like a skateboard just fine. try selecting by group (if the different peices are different groups) or material. you can give the board part a box map, for example, to get all six sides laid out. then give the wheels each a cylindrical cap, which will unroll the edge and show the front/back flat. if uvmapper is locking up on you, you have a problem, obviously. try running it with nothing else running, or reinstalling it. if it still locks up consitently for you, better contact steve cox about it.
