Quote - This looks a lot like self-shadowing to me, probably from ambient occlusion. Do you have ambient occlusion or ray traced shadows enabled for some of the lights? Try increasing the shadow bias and AO bias, that should fix it.

 

I am using the HDR IBL lights that come with Poser 8, which is using AO. I have noticed these results with all lights though. I have tried adjusting these values with no noticeable change. I am curious though as I haven't really played around with it much, what does the shadow bias dial do exactly?

Also, sorry if I am being a broken record here, but does anyone know why scaling an object smaller reduces this effect, and increasing the size of an object makes it worse? I just feel like understanding this will be the solution to getting rid of the edge shadows.
