Re: problem with bruteforce

Try values around 64, sometimes also this happens to me in dark or in "indirect" light areas.

Re: problem with bruteforce

I have done an experiment with 120 subd and occour the same .it s strange because the noise threesold is set to 0.002 do u tink the problem maybe in the light cache settings?

Re: problem with bruteforce

Excuse it was obvious...the render with IM is decent .i tried to render with bf thinking that gave me a more accurate and more detail but seems only slower sure i m wrong something

Re: problem with bruteforce

Could you show your light setup? Are using portals or smth?

Re: problem with bruteforce

Only hdri tried also with hdri vraysun with a problem of innatural reflexion in the ceiling hut this is another problem anyway the subdivision seems not affect the problem the settings of bf was 60 sub and light cache from 1000 to 2000 sub tried also universal settings .I think the problem is not the noise threesol because 0.002 should be an optimal value
