Follow-through and Overlapping Action are principles of animation. GraphKit’s Overlap overlaps your F-Curves based on the selection order. Optionally, you can overlap a loop without needing to extend the F-Curve’s length.

Target
- Selected F-Curves: targets selected F-Curves
- Selected Keyframes: targets selected Keyframes
Overlap Mode
- None: Overlaps F-Curves/Keyframes by itself (i.e. no consideration of other selected F-Curves). Useful for overlapping in a Loop.
- Object Selection Order: Overlap F-Curves/Keyframes based on the selection order of objects in your scene. That means every F-Curve/Keyframe for an object will be overlapped the same amount, the only overlap in the frames will come from when the object was selected.
- F-Curve Selection Order: Overlaps F-Curves/Keyframes based on their selection order, irrespective of the object. For example, use this mode if you want to overlap F-Curves belonging to one object or multiple objects.

Move overlapped keyframes to whole frame numbers.
Loop
Enabling Loop will not extend the animation’s time in either direction. It will shift their timing within the start & end frame range (i.e. starting at the beginning when the keyframes are shifted beyond the end frame).
Original Loop Length
When overlapping a loop, GraphKit Overlap creates one loop of keyframes at the beginning of your selection and one loop at the end. If you don’t want these keyframes to be visible, keep this property enabled. If you want the extra keyframes to be visible, uncheck this property.
