Instead of fumbeling some cycles rip off into Poser, it would have been better establish a Blender Bridge. That kind of a bridge for bringing your scene to Blender including cycles materials plus a return for creating morphs for your figures and objects. But all this would not justify an upgrade, for it can be simply done as a plug in. Poser has reached its limits. Unless they don‘t put effort into establishing real humans instead of toons equipped with a technolgy that allows realistic joint bendings, emotions and soft body dynamics. Poser will fall back to a niche software for the stuck in the 2k‘s click and load render people. Renders always advertise the software they use. Look here in the Poser gallery. Is this gallery make you want to buy Poser? Everbody will have his own opinion on this, but why is Poser no longer the market leader?
