HEY WAIT!

Before we assume that Poser can't render this scene - and send this poor soul off on a search for other software - What is the scene????

What were the render settings? Firefly - P-4? How complex was it? 

Are we talking about a 12 hour render? Or did Poser crash at 2 min - and the rest was just precieved as rendering time? Could it have been simply a corrupt texture - or a glitch in the OS that had nothing to do with Poser???

Computer Specs??? 

Not to say that this is not a Poser problem - but what can we really expect from any render engine. 12 hours in Poser - 1 hour in C4D? Not likely .....even a 50% reduction - 6 hours - still a long render for a single frame.

Try rendering in Poser in Layers - A few objects at a time and combine them in PhotoShop.

Do a test in P-4 or even preview render settings to make sure there is not an obviouse problem.
