Installing NVIDIA AI denoiser manually


In some cases, you may need to install the NVIDIA AI Denoiser manually. Here is how to do it:

  1. Close 3ds Max
  2. Install Corona Renderer using any installation method (automatic or manual)
  3. Unpack the Corona Renderer installer using the "unpack files" option - see this guide for step-by-step instructions: https://coronarenderer.freshdesk.com/support/solutions/articles/12000038849
  4. Once this is done, you should see the folder, where the files have been unpacked
  5. Go to "NVIDIA AI Denoiser" folder
  6. Select all files inside that folder and copy them
  7. Go to C:\Program Files\Corona
  8. Paste the files into C:\Program Files\Corona\optix folder
    Note: if you cannot find "optix" folder in C:\Program Files\Corona\, just create it.
  9. Start 3ds Max again, and check if the issue is now resolved.
