Since motion data has a separate processing pipeline than audio, it requires its own structure of busses. To handle both motion and audio, the Master Mixer hierarchy has been divided into two main branches: one for audio and one for motion. At the top of each of these branches are the following master busses:
-
Master Audio Bus - A top-level output bus where the final mix for audio data is performed.
-
Master Motion Bus - A top level output bus where the final mix for motion data is performed.
You can create an unlimited number of busses under each master bus to re-group the many different sounds, music, and motion objects in your project. When building a bus structure, the same features, rules, and conditions apply to both branches. Since audio and motion are handled differently, all sounds and music objects must pass through the Master Audio Bus and all motion data must pass through the Master Motion Bus.
