Where are the advanced OptiX denoiser settings like radius, strength, feature strength, etc. in 2.91? They were in the view layer settings in 2.83, but I can't find them any more.

2.91

2.83

  • $\begingroup$ You have to select one of the denoising options from the Render Properties tab (pick a denoiser and check the box), Once you've done this, the denoise settings will appear in the bottom of the View Layers tab. $\endgroup$ – Christopher Bennett Dec 7 '20 at 12:27
  • $\begingroup$ I did have the denoiser selected, but if you pick OptiX or OpenImageDenoise you only get an option of input passes without further options to tweak, unfortunately. $\endgroup$ – Jure Triglav Dec 7 '20 at 12:35

Figured it out. These settings are only for the NLM denoiser, not for OptiX (nor OpenImageDenoise). I somehow misread the docs at https://docs.blender.org/manual/en/latest/render/layers/denoising.html.
