A Keyframe holds the Poses applied to joints in a Model at a given point of time in an animation. Keyframes are interpolated between during animation playback.

Note, in most cases developers do not need to manipulate KeyframeSequences as the animation editor covers most animation functionality. However, in some cases a developer may wish to generate an animation from a Script or build their own plugin.


Keyframes are held within a KeyframeSequence and contain Pose objects. The poses are named in accordance with the BaseParts they correspond to and are structured in terms of joint hierarchy. This means each Pose is parented to the Pose corresponding to the part it is attached to. See below for a visual example.

Note, as Poses are named in accordance with the BaseParts they correspond to, animations require distinct part names to play correctly.


During animation playback the poses in different keyframes are interpolated between. This allows a smooth animation to be created without needing to define every frame. Note, the style of interpolation is determined in the Pose object. The Keyframe object merely holds the Poses at a defined point of time in the animation (Keyframe/Time).


Name Type Description

This property gives the Keyframe's time position (in seconds) in an animation. This determines the time at which the Poses inside the keyframe will be shown.
