OC 2020.1 Denoiser not working? Tweet

[Jazbee]

Hi, was anybody able to use the denoiser in OC 2020.1? I'm trying out all options - "Enable denoising ", "Denoise volumes", playing with sample values, "Blend" slider, turning the denoise render passes on (exported denoiser passes are just blank, black images) and the image always looks the same, nothing changes. The render does take a lot longer to complete when the denoiser is turned on though. And yes, I have "denoise" turned on in device settings.

I know this has been mentioned here already, but there was no conclusion.

Do you have a graphics card selected for denoising in the System tab->Open Device Settings window?

Yes, I mentioned this in my original post.

I'm using 2x 2080ti with newest drivers and tried selecting both cards for denoising as well as each one separately.

Are you using the PT kernel?

Thanks, that was the issue indeed!

I've been using PMC all the time. Switched to PT and Denoiser shows in the Octane viewport as a render pass and works as intended. Is there any real advantage on using PMC over PT apart from subtle caustic effects and such? If no, then I'll stick to PT, it's much faster anyway.

Unless you are doing some very picky caustics or extremely subtle and complex refraction, Path Tracing produces nearly identical results to PMC in significantly less time.

Thanks! That was what I assumed.
