its buried in the render options... basically, you have to sacrifice a goat prop to the poser & e-on gods, dance in circles around your computer - clockwise if you're in northern hemisphere, anti-clockwise in southern - all while singing the barney song... you know the one... "i love you, you hate me..."

if you do it just right and the Gods approve... you get that marvelous "spit it out" button - it decreases render times by 3/4!!!

Rarer than a hairy egg and madder than a box of frogs....
