The motion mixer pane provides a timeline-based view of the animation clips and motion effects of multiple characters. Animation clips are grouped into tracks, and additional effects can be applied to tracks to change the look and behavior of the final animation.
The motion mixer pane is populated with tracks and clips if you have a 
Motion Mixer SOP selected in the network editor. If you have another SOP selected, the motion mixer pane will be empty.
To open the motion mixer pane, click the 
New Tab icon at the top of a pane and select New Pane Tab Type ▸ Animation ▸ Motion Mixer.
See the motion mixer page for information on how to use the motion mixer to combine and edit animation clips.
Tracks, clips, and weights ¶
A track is a way to group multiple animation clips for a character, and is represented as a row on the timeline. A track can contain multiple animation clips.
Each track has an associated weight that is represented as a row below the track. The weight determines the extent to which the clips in the track contribute to the overall animation.
The headers in the motion mixer pane provide settings for configuring the tracks and weights. You can also 
click the track header, which opens up a menu with some of the functionality provided by the track header icons.
Note
If you can’t see the weight row, toggle 
at the top of the headers section.
