Creating constraints clips

Used with Constraint tracks, constraint clips let you animate the use of constraints.

Use constraint clips to make constraints active for only a segment of a take. For example, you can use a Parent-Child constraint between a cup and a character’s hand. You can create a constraint clip with the Parent-Child constraint to make the constraint active only when the clip plays, so that you can give the impression that the character is actually picking up the cup halfway through the animation.

To create constraint clips:

1. Drag constraints from the Asset browser or Scene browser to the Action Track list.

   Dropping the constraint into an empty area of the track list creates a new Constraint track with a constraint clip, and dropping the constraint onto a Constraint track creates a new clip on the track.

2. Make sure the Constraint track is below the track with animation the constraint is meant to affect.

   To move the Constraint track, click on its name and drag it up or down to the new location in the Action Track list.

3. If you have not already done so, set up the constraint.
