Denoise doesn't work

@nathanletwory ?

Packages are up to date.

Denoise doesn’t work (while it did in former versions).
See here:

@DavidEranen reportedly trouble with denoisers.

Hi @Charles,

Strange. First of all, I’d like you to try this:

  1. Change the sample amount to e.g. 1000.
  2. While it’s rendering, enable the Intel Denoiser.

Will it now denoise?

Second thing to try:

  1. Close Rhino.
  2. Delete all denoisers from %APPDATA%\McNeel\Rhinoceros\packages\7.0\
  3. Start Rhino and make sure no denoisers are loaded.
  4. Install the latest IntelDenoiser version and restart Rhino.
  5. Try to denoise.

Does it work now?


Both tries no success.


What about after you downgrade the IntelDenoiser from 0.6.3 to 0.6.2.



David, any news on this?

Version 7 SR7
(7.7.21151.13001, 2021-05-31)

Still no luck.


I don’t know what the problem could be. I’m also currently busy with other things, so it will take some time until I can get back to investigating this.

Have you tried deleting/backing up Rhino’s %APPDATA% settings folder? If I remember correctly it’s something like: %APPDATA%\McNeel\Rhinoceros\7\. When the folder is removed, Rhino will generate a new one with fresh settings.


Deleted the settings folder - no luck, still no result from denoise seen in the viewport.

Still no viewport denoise in

Version 7 SR8
(7.8.21160.5001, 2021-06-09)

Any progress on restoring the functionality?
