I think we don't have it "yet", simply because in the beginning, the Genesis of Poser was simply for what it says.  Posing.   An artist tool to help in the stead of a live model, and to be painted from, not used as its own medium.

As time passes, as we see, this has changed........ a LOT, but Poser still has its limitations.  It will take several more years in development I think, before it is completely geared to  a render only market.

Its come a long way baby, considering in recent times some phenomenal creators have made near photo quality stuff out of the program.   But, for under a 300 dollar mark purchase price, there really is only so far you can go.
