Animation Sequences

Overview

The Animation Sequence is a composite animation asset based on the skeleton asset. It is created by the Animation Editor and provides advanced features on top of the skeleton such as Retargeting, Root Motion, Notify, Marker-based Syncing and Curve Editing.

An Animation Sequence can be played standalone in the pipeline directly, or used for composite assets such as Montage, Blend Space and Anim Tree.

Creating Animation Sequences

Click File -> Create to open the Asset Creating window to create an Animation Sequence asset.

Asset Details

An Animation File needs to be specified in the Asset Details panel, and you can continue setting up the Animation Sequence by changing other items.

Property	Description
Skeleton File	Source skeleton file path (Read only).
Animation File	Animation file path.
Rate Scale	Play rate scaling factor.
Enable Root Motion	Enable root motion or not.
Root Motion Root Lock	The way to lock the root bone after the root motion is extracted. Ref Pose: Use reference pose. Anim First Frame: Use animation first frame. 0: Use standardized transform.
Force Root Lock	Force locking of the root bone, regardless of whether root motion has been extracted.
Use Normalized Root Motion Scale	Use normalized root motion scaling (To avoid the effect of non-normalized scaling on root motion results).
Translate	Legacy root motion related extraction settings. Clear Z-Axis and Clear X,Z Axes can be chosen.
Additive Anim Type	No Additive: Additive Anim type or not. Local Space: Data is in the local space. Mesh Space: Data is in the mesh space.
Base Pose Type	Skeletal Mesh Animation Reference Pose: Reference pose (Target skeleton). Selected Animation Scale: Specified animation. Selected Animation Frame: Specified animation frame.
Base Pose Animation File	Specified the animation file to use as the base pose.
Ref Frame Index	Specified frame.
Sync Group	Sync group.
Blend In Time	Blend in time.
Blend Out Time	Blend out time.
Blend Timing Mode	Use Absolute timing mode. Blend in and blend out time are not affected by the play rate； Use Relative timing mode. Blend in and blend out time are affected by the play rate and vary proportionally to the animation duration.
Start Trigger	Start playback trigger event.
End Trigger	End playback trigger event.
Break Trigger	Break playback trigger event.
Loop Trigger	Loop playback trigger event.
Custom Key Value	Custom key value.

Notifies

The Notify can locate specific points in Animation Sequences, and subsequently set events to occur at specific points to which Notifies are added.

The Notify typically adds effects such as sounds and particles to the Animation Sequence. It adds richness to the Animation Sequence and meets the needs of game creation in many ways.

For more details on Notify, please refer to Animation Notifies.

Animation Curves

Attach curve data to the animation, and the curves can be blended with each other. The logic layer can use these curve data to drive different effects (e.g. drive the intensity of IK, drive the material values, etc.). Using animation curves to customize the animation data is the semantic description of the animation data.
