I have installed Maya 2014 SP4 at home, this is a fresh install and was just trying to see if there are any problems with the new SP before I install it at work.
But for some reason, the install went OK, but when I looked under the Render settings there is no MentalRay, and then looking in the Plugins list, there are none there either?
Am I missing something ?
As of maya2014 installing mentalray is optional. It seems the option is off by default.
If you cant find mayatormr in the plugin list then you have a couple of choices.
1) Reinstall maya2014 and make sure to turn on the mentalray option.
2) If you are on windows look in the folder
C:\Autodesk\WI\Autodesk Maya 2014\x64\MentalRayPlugIn
MentalRayPlugIn2014.msi
and run it to install mentalray.
Hope this helps.
