Get a commercial or non-commercial version of MNPRX here.


The installation of MNPRX is intended to be the least invasive, so you won’t need to change anything in Maya or place files in any particular place.

  1. Extract the contents of the downloaded zip file anywhere you want e.g., documents, desktop, the project folder, you get the drill.
  2. Drag and drop the install.mel file from the extracted content into one of the Maya viewports. The install.mel will then run in the background and automatically add the MNPRX paths in your Maya.env file.
  3. If successful, a prompt will appear in Maya, asking you to restart the application, please do so to show all changes.
  4. Once you open Maya again, the MNPRX shelf will appear alongside the other shelves.
  5. To test if everything is working correctly, switch to the MNPRX shelf and click on the test button.
  6. If MNPRX has not been activated before, the activation prompt will appear.

A video showing this installation process can be seen below:

I can’t get the system to install using the install.mel file, what can I do?
It doesn’t usually happen, but if the install.mel installation doesn’t work, there are two ways of manually installing MNPRX:

Solution 1: Temporarily remove the content in the Maya environment file

  1. Copy the existing content of Maya.env to another file.
  2. Clear all the environment variables (which you have copied over already for backup) and save the file.
  3. Drag and drop the install.mel file again into the Maya viewport -> it should install successfully then.
  4. Merge the other environment variables with the new ones in the Maya.env file and save the changes.
  5. Restart Maya.

Solution 2: Insert the system paths manually to the Maya environment

  1. Enter the environment variables (available at the bottom of this page) into Maya. Make sure the shelf path is the first environment variable, replace #YOURMNPRXPATH# with the path where MNPRX is located and #MAYAVERSION# with the version of Maya you are using e.g., 2018, 2019.
  2. (Windows only) After entering the environment variables, run this mel script within Maya: setRenderingEngineInModelPanel "DirectX11"
  3. Restart Maya.
