Sorry svdl. I see these claims but they're wrong. Studio has raytracing, reflection, refraction, displacement , and they are properly implemented. It doesn't have animated materials. It can render reflected displacement. Try that in Poser 6. Advanced lighting options. Raytraced shadows it has, shadow mapping it has, IBL (not HDRI) and AO it has. As far as I know Poser 6 uses IBL not HDRI - similar but different. As far as IBL in Studio is concerned, it's a hack at the moment and has to be manually adjusted via the light scripts. No doubt it will be implemented properly at some point So, please. When saying Studio can't do things. Please do make sure you're talking about the current version and not one that is somewhere in the past or something based on "what so and so said. Thanks. On that note. Poser 6 offers some facilities that Studio doesn't (yet), the best of which is by far the materials room. Immensely powerful if you have the time and patience to learn it. There are other toys, like dynamic cloth and hair, face room, morph putty, setup room. Development and creation tools. All of which do not have their equivalent in Studio yet. Point being. Studio is studio and (currently) free. It is not Poser. It is not intended to be Poser. Poser is Poser and will cost around 189 dollars, it is not intended to be Studio. Poser is around a decade old, had more development time and has more in it and, as mentioned above. You pay for that. Studio is beta, around two years old in development and has less in it, but more is coming - eventually, some of which will have to be paid for.
