Tracks are the background on which you add and sequence clips in the animation mixer. There are six types of tracks in the
tracks are cream-colored and can contain only animation layer clips. When you create an animation layer, tracks and clips
for the layers appear automatically in the mixer: you cannot add new tracks manually. See Animation Layers for more information.
tracks are light green and can contain only action clips. See Actions for information about creating and using action clips.
tracks are light blue and can contain only shape animation clips. See Animating Shapes for information about creating and using shape clips.
tracks are sand-colored and can contain only audio clips. See Audio and Animation for information about creating and using audio clips.
tracks are light orange and can contain only clips created from cached simulation or animation files. When you create a cache
file, you can choose to have cache files be automatically loaded as clips in the mixer. You cannot use cache clips with other
elements in the mixer. See Caching Animated Deformations and Simulations for information about creating cache clips.
tracks are light purple and can contain only image clips; however, they are not defined as an element as are the other types
of tracks. See Manipulating Image Clips in the Animation Mixer for information.
You can sequence one clip after another on the same track or different tracks. However, clips cannot overlap on one track;
to overlap clips in time, they must be on separate tracks. See Working with Clips for more information.
Displaying Tracks and Their Information
You can toggle the display of tracks and their information in the mixer in any of the following ways:
Choosing the appropriate command from the View menu on the animation mixer command bar to determine which type of tracks to display.
Choosing from the animation mixer command bar to set a preference for the display options.
In the Animation Mixer Preferences dialog box, click the Tracks tab and select which type of tracks to display.
On the Tracks page, you can also select which track display options to view (Track Name, Transitions, and Track Tooltips).
Right-clicking a track and choosing . This opens the Animation Mixer Preferences dialog box with the Tracks page visible.
When you select a track, all appropriate commands are applied to it, such as inserting a track or accessing track controls.
A selected track is indicated by a white line around the track's control icon area.
Click the track's icon to the left of each track.
Shift+click the track's icon to select multiple tracks.
Ctrl+click the track's icon to toggle-select multiple tracks.
Tracks in the mixer are always grouped by type in this order from top to bottom: layer, animation, shape, audio. and cache.
When you add a track to the mixer, this grouping is maintained.
If you have nothing selected and you add a track to the mixer, it is added to the bottom of its type's "stack." For example,
if there are shape and audio tracks in the mixer and you add a shape track, it's added below the other shape tracks, but above
the audio tracks.
If you select a track, you can insert a track of the same type directly above it. For example, if you select an animation
track, you can insert an animation track directly above it; however, if you add a shape track, it's still added to the bottom
of the shape track stack.
To add a track to the mixer, do either of the following:
- You cannot add Animation Layer tracks directly in the mixer: they are created automatically when you create an animation layer.
- You cannot add tracks for image clips since they are not defined as an element as are the other types of tracks - see Manipulating Image Clips in the Animation Mixer.
TipTo add many tracks of the same type quickly, choose a command once, then middle-click the menu name to repeat the last command.
To insert a track of the same type
Either of these methods inserts a track of the same type above the current or selected track:
Changing the Tracks' Order
After you have created some tracks in the mixer, you can change their order. For example, you can group tracks, such as keeping
multiple shape tracks together for each part of the face (upper lip, lower lip, left eyebrow, right eyebrow, and so on). Or
you can move all muted tracks to the bottom of the track type (animation, shape, cache, etc.) so that they're not cluttering
You can move a track only where there are other tracks of the same type. For example, you can't move a shape track to be between
animation tracks. This is because the tracks are organized into different parent containers that can't be combined.
You can reorder all types of tracks except for tracks that contain image clips.
To change the order of a track, click in its icon region and drag it to its new location among other tracks of the same type.
A black bar indicates where the track will be placed.
The new track order is also automatically updated in the model's Mixer > Tracks folders in the explorer.
In the image below, the Mixer_Shape_Track is being moved down below Mixer_Shape_Track3.
Muting and Soloing Tracks for Playback
As you work in the mixer, you can play the tracks in your scene as usual using the buttons in the Playback panel or by scrubbing
the timeline. You can also use the mute and solo options to concentrate on specific tracks:
Activate a track's Mute option (click the button) to stop it from playing back with the rest of the scene. It turns light orange when active. When you do this, any
clips on that track appear in a light gray to show that they're inactive.
Activate a track's Solo option (click the s button) to play back only that track. It turns green when active. You can solo
more than one track so that only the tracks you specify play back.
You can also set these options by right-clicking on a track and choosing or by selecting the track and choosing from the mixer's command bar.
If you move a clip from a muted track, the clip will stay muted. To work around this, mute and then unmute the new track on
which that clip is located.
In addition, you can mute individual clips. To mute a clip, right-click it and choose , then turn off in the property editor that appears.
Removing a track deletes it together with any clips that it may contain. This removes the tracks from the mixer, but it does
not delete the sources for any clips on the tracks.
To delete tracks
Do either of the following:
Right-click the track you want to delete and choose . This deletes only the track on which you right-click: any other selected tracks are not deleted.
Select one or more tracks by clicking on their icons (Shift+click for multiple tracks), then choose Track from the mixer's command bar or press Delete.
Choose to clear all tracks from the animation mixer.
To delete empty tracks
Choose from the mixer's command bar.
This removes all tracks of any type that have no clips on them, including empty tracks within compound clips.
