Hey,

as you can see I have some noise in my pic, rendered with Mental Ray. I've tried a bunch of settings, but I can't get rid of them. I've tried:

Anti-aliasing min,max 1,3
Filter: Mitchell
contrast threshold 0.01
max settings for raytracing
Final gather rays up to 3600
increasing the min and max radius

but still no luck (and now we're talking like 8 hours render time).

Any ideas?
