Click the Double Sided Column.
Input 0 to turn off all selected items at once.




Install plug-in, if you do not see Arnold options
Keep in mind that Autodesk did not develop Arnold; it is a plug-in for Maya, so you may have to enable it in the Plug-in Manager before you can see it as an option in your Render Settings window.
     To enable the plug-in:  Windows->Settings/Preferences->Plug-in Manager
     Check both the Loaded box and the Auto Load box next to mtoa.mll
     (Located near the bottom of the list.)
