Well, you are saying the opposite there from my experiences with the MegaPov
kind.  Perhaps you are talking of official POV-Ray though.

Yep, I'll check another render out using your advice.  What I did was to use
the recent radiosity settings Mike Hough and others had been using for those
smoothed shadowed hemispherically lit Arnold-like things, figuring if it was
good enough for that....
The main point I wanted to make is how a radiosity rendering could
potentially be worthless compared to a much speedier rendering.  I mean 16
times slower than a comparable radiosity render (5.25 hours vs. 1/3 hour!)
with recursion at 1 is no doubt all in vain.  It's sure to vary greatly
scene to scene but I think people should be made aware.  The general rule of
small test renders always applies.

Thanks for the helpful hints.

Bob
