Description
this is a GI test with (you guessed it already) brazil r/s, (yepp *g*)...
scene is lit entirely by skylight, indirect illum. params:
bounces: 6
shade rates: min -4 max -1
sampling rate 80 (!)
aa: min 1 max 2 (ok, could go higher, but didn't matter here...)
render time on my tb 700: 5h 7min...
so after 5 hours the image is still not clean...hmm any ideas what i could do to improve render time and/or image quality (besides going to a sampling rate as high as 100 *g*)...? thanks!

the lighting is great, can't give you any advice since i'm more of a bryce person... but that lamp is waaaay too big :)

ehm this sounds maybe dumb to you, but set the gi sample-rate to min -3 max +1, and samplerate down to 40

thank you, but i think this won't help... you know neil blevins? visit his site www.neilblevins.com and click an cg education...there is a tutorial about "undersampling"... if i would increase max shade rate to +1 it would tremendously increase render time and create grainyness...

how bout trying some fake real effects? FRFX? 3 hours of setup but 1 minute per fame :)
