Trying to switch to Brute Force, but still too noisy for the rendertimes.

Hi,

I'm looking at moving over to the Brute Force/Light Cache method to simplify our scene setups.

I've gone through the threads and cheatsheet, but still can't seem to get a noise free render without massive rendertimes using the BF/LC method.

Attached are renders/settings and samplerate that I have been using. At the moment it is taking the same amount of time to render as our usual IM/LC method, but way noisier.

Any ideas on what to try to speed up and smooth (apart from whacking the denoiser element on it?)

Thanks!

start from default settings. MSI of 16 is on the high side. also with sample rate element like this max image sampler subdivs might be lower. sharp aa filter may pronounce noise as well.
and it will never be as clean as IM in reasonable time. denoise it or just consider the switch to BF as transferring man hours (setting good IM) to machines (rendering) and getting better quality as a freebie.

Thanks for that, turning on probabilistic lights and changing the filter to vraylanczos seems to have cleared it up a bit.

I'll keep and playing and see what I can get out of this method.

...turning on probabilistic lights...

If you're on 3.50.04 then try the new adaptive lights

We are upgrading in the next month to 3.50, so hopefully that should speed everything up as well.
