trying another render with some setting adjsutments now.. I think my shadows are extremely dark despite using your settings posted * 3 lights total, 1 10% IBL white / 1 main light, 1 side pink light.

this was with depth maps ( trying now with Raytrace but still same darkness.. )

not sure whats up with it.. Shadow is just 1.0 as usual on the 80% light...
