Only animated tracks of the selected object are highlighted in the Hierarchy window of Track View - Curve Editor.
This is indicated by the deletion of the (R#) suffix from each baked track's name. This saves the retimer's changes to the tracks permanently and removes the tracks from the retimer's control. In the cluster of Retime tool buttons near the top-left corner of the Track View window, click Bake.Activate a retimer that has tracks assigned.When you're satisfied with the retiming, you can easily bake in the adjustments to make them permanent and remove the overhead imposed by the retimer. Then, even if the objects aren't selected, dragging the markers affects their motion. Note: You can use the same retimer on any number of different objects just select them and click Assign. In general, if you're scaling keys in time only, the Retime tool gives you more options and more-predictable results. The Retime tool supports multiple scaling regions the Region tool supports only one.The Retime tool supports Ease In/Out options for acceleration and deceleration the Region tool does not.
With the Region tool, expanding or moving the region horizontally mixes the affected keys with other keys outside the region, while with Retime, the region remains intact and keys outside the scaled region simply move aside.The Region tool scales both time (horizontally) and value (vertically), while Retime scales time only.The Retime tool is somewhat similar to the Region tool in that both scale animation, but they differ in a several ways: Retimers are saved and loaded with the scene.The curve's track is assigned to the active retimer.The curve's track is highlighted in the hierarchy list.When the Retime tool is active, an animation curve is visible in Track View only when both of these conditions apply:.
The Retime tool is based on the Ease curve, so it not only moves keys but warps the time between the keys as well.Please note the following important aspects of Retime tool behavior:
