Neat. Three hours, eh? I'll assume you need portals to get it to render that
quickly, even on a quad-core. How do you set that up for toroidal lights
though? Do you bound it by a sphere? Do you approximate the tori with a mesh?
Or maybe you have other tricks up your sleeve...

No portal. There is too much light sources and portals would be too slow. I use
high number of primary diffuse rays (12).
Attached the source of the scene.

Fidos.

Can I ask how many passes this scenes took?
I'm just curious as I have it running atm and its on pass 14 and still very
very blurry. I dont have the CPU power you do but its been going to for
twice as long allready.

Around 28 passes on 4 cores if I remember well. But, 28x8 passes is not
equivalent to 56x2 or 112x1 passes. Better is 28x8 passes.
H. Karsten point out that in its post :
http://news.povray.org/web.49563c4fbe8b348c20776f0%40news.povray.org
The problem is in the way mcpov choise the pixels to trace in order to reduce
noise.

Fidos

Okay well I left it on over night (3.1gig dual core machine) and its now
done 76 passes. Its still very blurry compared to yours. I'll have a read
and see if I can work out what is going on in that link you sent.
Thanks for the info!
Cheers Dre
