@Whatte: Yes, this is a well known error based on how Poser handles light. Especially with DAZ figures (don't know for other figure-geometries). There are some tricks to get a resonable result. Ambient occlusion, for example, may help. Or not to use infinite light and setting the light to raytrace mode. May help. Not in any cases. If you have P7, try Pointlight for lights behind the figure. One or the other works for me, most often. But actually I try to avoid using Posers render-engine (not allways possible, because other apps do not have support for Posers shader system).
