OK, I've done this a few times.
Some additonal information.

The original .PZ3 was created in Poser 5.
The model has RealSkin shader information attached.
Oh, BTW, face_off its actually StephPetite wearing a V3 texture.(oops!)

We fired up Poser 6, loaded a .PZ3, deleted the loaded lights and selected a Poser 6 IBL AO lights setup. We try and render and we get the all too familiar attached image #1.
