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

Are you refering to the preview, where this is normal, or the rendered image where this is not?

Actually, it's the same in both preview and render. See through all the way, from "inside" angles.

Check render setting to see if you have "Remove back facing polygons" selected.

Holy Shinola! That did it! Thanks a lot! Thanks thanks thanks :)

a one sided polygon will not display in preview when viewed from the back but it should render ok. remove backfacing polys and that polygon is not rendered at all, and so is not visible.

Remove back facing polys can save some render times but in other cases it causes problems.

Yeah, thanks, I had to learn this the hard way. Oh well, at least I learned something. :)

It is also a good idea to check that "normals forward" is selected for the shader in the material room
