Hi, I've been trying to render my animation as an AVI file in P5 using the Firefly renderer but all I get is a blank grey (background) picture (ie no props, figures, ground, NOTHING)! If I render the same scene using the P4 renderer it works fine. The raytracing toggle etc... seem to have no effect - still a blank grey picture! Rendering just a single frame from the animation either into the document window or into a new window using firefly works fine. I've installed the SP1 - did it do this before the patch? Am I missing something obvious? Any help VERY much appreciated.
