Mayatomr not available after uninstalling mental ray for Maya 2015 SP2 plug-in patch (windows-only)

If you uninstall the mental ray for Maya 2015 Service Pack 2 plug-in patch on Windows, and find that Mayatomr is no longer appearing in Maya, you can work around this issue by modifying the following file:

C:\Program Files\Common Files\Autodesk Shared\Modules\Maya\2015\mentalray.mod

And changing these lines from:

+ LOCALE:en_US mayatomr 3.12.1.12 <MENTALRAY_DIR>
+ LOCALE:zh_CN mayatomr 3.12.1.12 <MENTALRAY_DIR>
+ LOCALE:ja_JP mayatomr 3.12.1.12 <MENTALRAY_DIR>

to:

+ LOCALE:en_US mayatomr 3.12.1.12 C:\Program Files\Autodesk\mentalrayForMaya2015\
+ LOCALE:zh_CN mayatomr 3.12.1.12 C:\Program Files\Autodesk\mentalrayForMaya2015\
+ LOCALE:ja_JP mayatomr 3.12.1.12 C:\Program Files\Autodesk\mentalrayForMaya2015\

And re-starting Maya.
