WOW! I just downloaded and tried grouper what a timesaver! two days ago I did a scene with two figures, clothing, and props, took me over an hour to properly group them. I tried grouper on the same OBJ file and it took 10 minutes and while I still had to load the trans maps and adjust the materials in Bryce what took me over an hour and a half two days ago took me less then half an our tonight. I'm so happy! a program that acualy works, and even better it's free!!!
