Orientation (Rotation) Constraints

You can constrain the rotation values of one or more selected objects to another object without changing the location of the constrained objects. A rotation performed on the constraining object is also performed on the constrained objects. For example, you can make a group of people’s heads all move in sync by animating one head and then constraining the rotation of all the others to this head.

To constrain an object’s orientation

1. Select one or more objects to be constrained.

2. Choose Constrain > Orientation and pick the object that is to act as a constraint.

3. In the Orientation constraint property editor, you can set a Rotation Offset between the centers of the constrained and constraining objects by entering X, Y, and Z values in degrees. See Creating Offsets between Constrained and Constraining Objects for more information.

4. Select the constraining object and rotate it as desired. The constrained objects also rotate.

You can also set rotation limits for an inverse kinematic (IK) chain in its Kinematic Joint property editor—see Setting Rotation Limits
[ Character Animation ].
