I understand what you're saying. The problem is that I'm visually used to certain effects in poser without GC, like the soft diffuse shadows on a ball. I now understand that that is actually wrong, like Stewer showed with his moonpicture and I discovered also this afternoon. ( talking about an AHA-erlebnis)
But shadows like that only exist in outerspace or in a black-velvet clothed room, so we always need IBL with ambient occlusion or use IDL in combination with GC, to get softer and realistic shadows.
I still have to work on the dynamic hair shaders,but I'm making some progress.
Using inverse square falloff is also a good tip, I forgot about that one.

Best regards,

Bopper.
