Hi rosie,

a very cool woody'esque discovery! How did you trigger this hidden feature in Bryce, the "render final scene backwards before composition button"? 

From an engineering POV, maybe you need to turn the plug of your PC in its socket by 180 degree, to render with a positive phase displacement. But don't do this at home!! ;P

Whereas I like tjohn's concept of an "unrender button" very much. :))
