User Interface


The Maya Legacy Connector is no longer supported. All users should move to Maya Native.


Once the plug-in is installed, users must sign into an Omniverse server. Users can do so from two places in the Maya plug-in:

Plugin Menu
  1. Connections are made to Omniverse via the connection dialog.

Users can take 2 routs to the connection window. 1. From the Omniverse Main Menu drop-down users can go directly to the connect menu. 2. From the Omniverse Shelf you can quickly get to the connect menu.
