Hey Spakni, I DID try to keep 'Remove backfacing polygons' checked but that didn't seem to help. With the WedgeCut hair if you remove backfacing polygons you see large gaps where there should be the underside of the hair object. I've also played with trans edge values and am used to using the Trans Min and Max. I haven't gone through my entire library of hair but I'm pretty sure this problem comes up again and again. The Princess Hair (that long braided pony tail thing) also shows irregularities, Koz's WaveHair, Shorthair, Mehndi Elfhair. Strange that other Koz productions seem to work fine. I just always liked the WaveHair package. You can shorten it up and it clears the shoulders for almost any pose. I've tried UV mapper to fix the object and played with some of the settings in the material room and when I couldn't get it to render right thought to post here. I love reading the chains here anyway;) Thanks all, Rance
