I have a particular avatar made in IClone 5.5 by BigBoss and Dicho and it's important for my filmmaking. However I have this problem with animating it. Whenever I do certain flexible animations with it that make it bend in its midsection a line of clipping appears in its lower torso. I don't know how to fix this problem myslef. Has anyone else ever had a problem like this? Does anyone know of any possible solutions to it I can apply myself?

This is what it looks like as you'll notice the bleeding through of his lower half into his exact midsection as he is bending forward. I hope this image helps diagnose the problem.
