Installing the NVIDIA AI Denoiser (Optix) manually

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

  1. Close 3ds Max

  2. Install Corona by following the standard installation instructions 

  3. Unpack the Corona installer using the "unpack files" option

    See the Installing Corona Renderer manually using the "unpack files" option article for step-by-step instructions.

  4. Once this is done, you should see the folder, where the files were unpacked

  5. Go to the "Corona" folder and then to the "optix" folder

  6. Select the .dll file inside the "optix" folder

  7. Go to C:\Program Files\Corona

  8. Paste the .dll file into C:\Program Files\Corona\optix 
    Note: if you cannot find the "optix" folder in C:\Program Files\Corona\ , just create it.

  9. Start 3ds Max again, and check if the issue is now resolved
