Opera, not coffee, Red Bull. I've had five today! Heaven forbid the FDA finds something wrong with Red Bull. I've got stock in that company. Per: firefly assembly level, I will still render outdoor scenes in V5I for ecosystems, trees, etc., but I am absolutely impressed with the quality (read: non-clayness) of the IBL - it makes Poser a completly different program. And yes, P6 with the bells and whistles I've used so far is REALLY fast.
