Damping the speed of Rigid Body transformation

You can use the Rigid Body setup pane to create delays or to smooth jerky movements in animation created by constraints.

To damp (or slow) the rotation/translation speed that the constrained object transforms the parent object:

1. Create a Rigid Body constraint. See Using a constraint to create a Rigid Body for more information.
2. Once you have assigned Source and Constrained objects to a Rigid Body constraint, click the Setup tab in the Constraint settings.

3. Enter a value in the Time Before Recovery field.
4. Enter a value in the Recovery Damping Time field.
   Note: MotionBuilder measures these fields in frames per second or timecode format, depending on the settings in the Global Controls.
