Denoiser not working with RT?

[Alex_M]

I can't make the denoiser work with RT. Is it supported when rendering with GPU? All render elements get generated during rendering and I can see them in VFB except for "effectsResult" where the denoised image usually is found in Adv. Manually clicking on Update in the denoiser element didn't work either. I'm using the nightly by the way, check version in signature.

Hello,

Are you using DR or out of process rendering? If that is the case - the denoiser is not updating correctly due to a bug in recent nightlies. We should have a fix ready soon.

Best regards,
Yavor

No, not using DR. :/

[yavor.rubenov]

Could you try a more recent nightly then - in today's nightly(27409) the denoiser seems ok.

Today after installing a GTX 1080 ti the issue went away. Maybe the GTX 980 didn't have enough power or memory to compute it? Shouldn't it fall back to CPU denoising in such cases though?

[yavor.rubenov]

Denoiser falls back to the CPU if there is no suitable device and also prints a message about that. Something else changed when you added the new GPU..

I have the same problem with denoise render elements separately. Single pass on RGB only works fine
