It sounds like a few things could be happening. Did you morph Jessie's body before conforming the bikini? If so, it's possible that the bikini doesn't have the same morphs. For example if you gave her huge breasts that the bikini can't accomodate, there will be poke-through. Some models will bloat or balloon at render time if polygon smoothing is turned on. Look at your render settings, if poly smoothing is on, try again with it turned off. Any P6 users have other clues that might help lzy724?
