Segments
A segment is a group of animations and layers that is exclusive and independent of other segments. You can see segments like a scene within Timeline.
When you need to create animations that do not share the same layers, you can create Segments. A segment is an independent set of animation and layers.
When you play an animation in a segment, all currently playing animations in the previous segment will blend out, and the first animation of all layers of the segment will start playing.
Shared segment
If you need animations running that will not transition when switching between segments, you can create a "shared segment". Any targets in layers created in the shared segment will be reserved and will not be available to be used in segments.
