Rendering issues in poser 9 [SOLVED]

jrcobra2001_2f25c31917

I'm not sure how to search for my specific issue because every time I do I get the same topics or websites that have nothing to do with my problem so here goes.

I'm using poser 9 and I am encountering a issue where the inside of clothing like say a jacket for example is see through. If I only put a few things in and render it comes out fine but as I add things this inevitably happens and ruins the render. It happens with other figures too but is most noticeable with clothing.

Is there some setting I should be increasing? I really don't want to go playing with settings without knowing what they do.

Edit: Solved it apparently I misunderstood what back facing polygons meant. Turning it off in render settings fixed the problem.
