I'm having some trouble getting this item to look acceptable in rendering engines other then Poser. To do so means understanding how the texturing is constructed, and I don't follow it. If we take just the hair base, it seems to be made up of three layers, outer, middle and inner. However, the first two of these are set in Poser to be 100% transparent with no transparency map. Which, as I understand it, means they are completely invisible. So why are they there? Any help gratefully received.
