To set up mental ray network rendering
If you have multiple versions of mental ray standalone installed (not recommended), each must have their own TCP port number in the services file to avoid conflict. For more information, see Network render with mental ray for Maya.
The mental ray satellite for Maya packages have the same name. Therefore, you must manually uninstall previous versions of mental ray satellite before installing the current version of mental ray satellite.
On Mac OS X, you need to use the mental ray satellite uninstaller in the mental ray satellite folder to properly uninstall this product. If you delete the mental ray satellite folder, port and machine associations may not be updated properly once you install the latest version of mental ray satellite.
