Follow Track Constraint
By default the Follow Track constraint is making objects have the same position at a frame as the track has. The motion of this object happens on a single plane defined by the camera and the original position of the object.
- Active Clip
Receive tracking data from the scene’s Active Clip. If unchecked, an option appears to choose from the other clips.
- 3D Position
Use the 3D position of the track to parent to.
Parent to the undistorted position of the 2D track.
- Frame Method
Defines how the footage is fitted in the camera frame.
Select the camera to which the motion is parented to (if empty, the active scene camera is used).
- Depth Object
If this object is set, constrained objects will be projected onto the surface of this depth object which can be used to create facial makeup visual effects.
- Constraint to F-Curve
Creates F-curves for the object that copies the movement caused by the constraint.
Controls the percentage of affect the constraint has on the object. See common constraint properties for more information.
