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.

OpenSubdiv smooth Mesh Preview Crash

**Update. This issue has been resolved in Maya 2015 SP2**

Maya 2015 may crash turning on Smooth Mesh Preview (3 key) for some meshes if the Subdivision Method is OpenSubdiv.

To avoid the crash either delete or rename the UV Set named ‘map11’, or change the Subdivision Method to Maya Catmull-Clark.

1. Select the mesh
2. Open the UV Set Editor. Create UV’s ->UV Set Editor
3. Select  the UV Set named “map11”
4. Delete or Rename

or 

1. Select the mesh
2. Open the Attribute Editor for the mesh shape.
3. In the Smooth Mesh attributes change Subdivision Method to Maya Catmull-Clark

Thanks to QA for the tip on this!

Cheers!
