How to install Corona Renderer manually using the "unpack files" option?


Sometimes, installing Corona Renderer manually may be the simplest solution to some installation issues. Here is how to do it:


1. Uninstall Corona:

To avoid issues, it is best to uninstall Corona Renderer first. To do it, simply go to the Windows "Programs and Features" or "Add or remove programs" list, and find "Corona Renderer for 3ds Max". 


2. Unpack the files:

  1. Run the installer
  2. Select "unpack files" and specify the location where the files should be unpacked
  3. Proceed with the installation
  4. The folder with the unpacked files will automatically pop up once the installation is finished


3. Install the plugin:

  • Corona Renderer 5 and newer 
  1. Make sure 3ds Max is closed
  2. In the location where the files have been unpacked, locate the "Autodesk\3ds Max 20XX" folder corresponding to your 3ds Max version
  3. Copy the "3ds Max 20XX" folder into your "Autodesk" folder (usually C:\Program FIles\Autodesk\)
  4. Copy the "Corona" folder from the folder the files were unpacked to into your C:\Program FIles\ folder
  5. Once all of the above is done, Corona Renderer will appear on the list of available renderers in 3ds Max


  • Corona Renderer 4 and older:
  1. Make sure 3ds Max is closed
  2. In the location where the files have been unpacked, locate the "3ds Max 20XX Plugin" folder
  3. You should find a few .dll files in there, and two folders: "scripts" and "plugins"
  4. Select all of the files inside the "3ds Max 20XX Plugin" folder, and copy them into your main 3ds Max installation directory (e.g.: C:\Program Files\Autodesk\3ds Max 2018\):
    • The .dll files should end up directly in the \3ds Max 2018\ folder
    • "plugins" folder should replace the existing "plugins" folder
    • "scripts" should replace the existing "scripts" folder
  5. Once all of the above is done, Corona Renderer will appear on the list of available renderers in 3ds Max


Note #1: The folder structure has changed in Corona Renderer 5. In rare cases, this may necessitate adjusting permissions for the C:\Program Files\Corona folder and all its contents should you encounter issues with the error referencing a path to Corona files.


Note #2: in some rare cases, Corona Renderer does not appear in 3ds Max even after manual installation. The solution is to copy the content of Corona Renderer's "plugins" folder into 3ds Max 20XX\stdplugs directory instead of the default 3ds Max 20XX\plugins directory.


Note #3: the additional files (NVIDIA AI Denoiser and Material Library) do not have to be downloaded during the installation. You can also install them in offline mode. See:
