I purchased, 3d-Worlds Core Kit for my poser 5, way before P6 was told. And did do ok, no problems. Now that I have P6, I am encountering problems with the kit. No matter what light I use, I get these square black spots on my terrain. I am now clueless what it could be. Here (Image) I am using IBL AO. But even when I use Infinite, Point....the results are the same.
