CreationΒΆ
Click on the Create Manipulator button in the Rumba shelf in Maya.

Then select the desired type of manipulator in the menu.

The Rumba Default Manipulators
option will automatically create a set of ready to setup manipulators respecting the naming convention.
Note that a controller must be in the active selection to create a manipulator (this is also true for Rumba Default Manipulators
).
