Hello Arjo Boris and Jason,
Thanks for the explanation, and the warnings.
I checked the view properties, GI effects are already selected in the
Effect/Box. Still, when I watch windows taskmanager CPU activity drops to
50% on both processors as soon as GI postprocessing starts.
This worries me a little because I have reserved time on a small renderfarm
(10 cpu's) and I'm afraid that postprocessing may take forever (read many
euro's) on high res images. Can anyone take away my fears?
Regards,
Frank
