Just to add a different thread to this, I was looking at the Pixels 3D site, (the people behind Firefly), and their ShaderMaker Pro, and I notice that most of the lighting and material changes being promoted for Poser 6 are actually part of the latest version of ShaderMaker and Tempest (Ambient occlusion, subsurface scattering of light etc. This would make sense - part of the benefit of licencing an existing produce would be to get these updates. It could also mean new lighting types - their website seems to be very proud of their area lights
