> Does anyone on this list have any experence with Pov-ray over a oscar
I've done tonnes of this sort of thing, doing it right now in fact.
There are some details here
for splitting up single frames. Mostly though I use it for animations
on up to 200 processors.
However, you haven't given nearly enough information. In particular
what OS is you cluster running? How does cexec do? Can you render
the image on one machine?
