In my feeble attempts to unravel a mystery I became frustrated. I had tried to use SSS on the characters and and continued to have splotches of white. I thought it was as a result of the splines being to close together. I guess I was half right. Notice the first picture around the bottom of the lip. I adjusted the splines so many times I was about to completely redo the lip area. Since SSS uses the ability of the patches as light passes through it, I realized it is how close the patch is behind the lip. I had the inside lip and mouth right next to the lip. Notices the second shot. I have been able to rid of the splotches.
