Hello

I try to render out a glass with a fluid in, the background is black. I have a lot of noise in the highlights...
I tried DL and PT and come to render times from 15 minutes one gtx 980 and still have some noise...
Especially the blurred parts out of focus are very noisy ...
Is there a trick how to get rid of the noise??
I am using 2.16.2 on mac 10.10.2

thank you very much for any help

Martin

could You give us any render?

Hey glimpse

here is the pic ...
I have to animate around that environment ... so I am really concerned about the render times ....
Thanks for your help !

cheers Martin

I used standard settings for path tracing and I stopped after 6 min with around 740 samples ...

lot of settings and options here. How do you illuminate this? What about gi_clamp, coherent ratio, spec depths, etc..

I illuminated with an hdri ...and pt which I stopped after 5 minutes
But I will need in my animation nice blurry effects with glas and liquids

what kind of algorithm do recommend ??
The attached one is with DL and 760 samples and the blurriness is not so nice

thanks for your help!!!

DL or PT. Hard to estimate results without materials. But looks very noisy. You should check it under different lighting situations. Best way to understand what causes this noises. I do that everytimes and never giveup.
