The Master Motion Bus Hierarchy

The Master Motion Bus hierarchy is a structure of motion busses through which the motion objects (or sound objects via audio to motion in their Motion tab) in your project are routed. It consists of two levels with different features:

Master Motion Bus - The top level element in the hierarchy that determines the final motion output, typically controller vibration, of your motion or, potentially, sound objects. While you can move, rename, and delete the other busses that you create, the Master Motion Bus can't be renamed or removed.
Motion busses - One or more busses for routing motion or, potentially, sound objects to a motion output device, typically a controller. They are grouped under the master motion bus and can be renamed, moved, and deleted.

	Note
	You can generate motion data from a sound object, including music files. For more information on generating motion from an existing sound object, refer to Generating Motion from Existing Sounds.

To help you easily identify a bus in the interface, Wwise uses a unique icon to represent it.

Motion Bus

By default, the Motion FX objects from the Actor-Mixer Hierarchy are routed through the Master Motion Bus. However, as you build your output structure, you can systematically route objects through the busses that you create.

	Note
	You can change the default motion routing for your project in the Default Setting dialog box. For more information about these default settings, refer to Defining your Project Settings.
