I migth be wrong but I think the only new feature with lighting is the possibility to use HDRImaps as IBL-lights, the renderer has some new features as irradiance caching and texture filtering, and there are some changes in the material room. But poser7 scenes can be loaded in Poser6, Poser6 will complain, but it will load. I can't verify this anymore because I don't have Poser6 on my new computer, but on the old one I had Poser 6 and Poser7 installed without any problems. I know there are some problems with pythonscripts like wardrobewizard, because poser7 uses a newer version of python and has some new functions, so poser7 scripts cannot always be used in poser6, and it's the same the other way around.

Bopper.
