I use Carrara 5 Pro to render all my poser related stuff. It works just fine and it's a hell of a lot easier (for me anyway), getting good results out of Carrara than it is out of Poser. I'm just much more comfortable with the way Carrara does things. My gallery has a bunch of Carrara renders for the curious. As a sidenote, though I will say that C5 Pro seems noticeably slower than C4 when dealing with my various scenes. C5 does have the edge in making it easier to import my Poser 6 content (I had to "trick" C4 to get it to import from Poser 6), just slower on my machine than C4 was. End results on both were quite good though.
