The Propagate tool copies the pose of the selected bones on the current frame over to the keyframes delimited by the Termination Mode. It automates the process of copying and pasting.
Options
Termination Mode
Modes which determine how it decides when to stop overwriting keyframes.
While Held
The most complicated of the modes available, as it tries to guess when to stop propagating by examining the pauses in the animation curves per control (i.e. all F-curves for a bone, instead of per F-curve).
To Next Keyframe
Simply copies the pose to the first keyframe after (but not including any keyframe on) the current frame.
To Last Keyframe
Will simply replace the last keyframe (i.e. making action cyclic).
Before Frame
To all keyframes between current frame and the End frame option. This option is best suited for use from scripts due to the difficulties in setting this frame value, though it is possible to set this manually via the 调整上一步操作 panel if necessary.
Before Last Keyframe
To all keyframes from current frame until no more are found.
On Selected Keyframes
Will apply the pose of the selected bones to all selected keyframes.
On Selected Markers
To all keyframes occurring on frames with Scene Markers after the current frame.
End Frame
Defines the upper-bound for the frame range within which keyframes will be affected (with the lower bound being the current frame).
