Hi all. I need to ask this (most probably stupid) question. I'm rendering lots of models in Poser Pro and noticing this thing all the time. The clothes, normal conforming clothes, are transparent on the inside. If I look at the clothes on the model from the outside, the are solid, but the cloth on the inside shows the background. I've seen this happend to hair as well, it gets transparent from certain angles and doesn't show at all. I can have this without any certain settings. At the most I've added SSS to the character model through the script.

Is this a lighting issue? Or refraction? What could it be?
Thanks
