How to install the NVIDIA GPU AI Denoiser in offline mode?


In Corona Renderer 3 or newer, our universal installer attempts to download and install the NVIDIA GPU AI Denoiser automatically, provided that a supported NVIDIA graphics card is detected. This is however sometimes unwanted or impossible - for example in the case of batch installing Corona Renderer on a render farm. In such cases, the denoiser package can be downloaded once, and then distributed along with the installer. Here is how to do it:


  1. Download the universal installer for 3ds Max or Cinema 4D here - https://corona-renderer.com/download/

  2. Download the NVIDIA AI Denoiser package for:
  3. Place the downloaded NvidiaAiDenoiser file next to the universal installer (e.g. if the universal installer is located in C:\Downloads, then place the NvidiaAiDenoiser file in C:\Downloads as well):

  4. Run the universal installer and proceed with the standard installation.
    Note: There is no need to use the "Custom" installation type, or to check or uncheck any options. This will work even if you simply press the "next" button a few times to finish the standard installation.

  5. The universal installer will install the NVIDIA GPU AI Denoiser from the local folder instead of downloading it.


Note: If you do not see NVIDIA AI Denoiser in your host application it is likely that your graphics card is not supported. See: Hardware Requirements


The NVIDIA GPU AI Denoiser installation can be also safely cancelled, or skipped completely - See: How to install Corona Renderer without additional data?
