The PR3 shader is better, has a clear structure where to change what, and works well with Parmatic. I worked a while with PR2 as well and used PR3 only recently, but I surely will never go back. The only thing I plan to change is to have another PM-value for the AO-bias, because the standard is too fine i.e for the Girl.

But should I continue to use material based IO, BB? If I remember right, Poser 7 with SP3 does have an usable AO on lights, which would be better than on the materials?
