Hello, I use Maya. I managed to rig full body and upload it and it worked fine in SL. However when I rig a piece of cloth lets say a jacket or a skirt, "calculate weights" button disappears when I check skin weights. When I was rigging I selected each bone (all 26 of them) and applied smooth binding. Can you suggest any work around or solution to this problem? Edit: I found the solution. On the smooth bind options window I unchecked "remove unused influences". That did the trick:)
