orientConstraint

Orient Constraint Attributes

Lock Output: Specifies whether or not you can directly manipulate an object’s constrained channels. For example, when the orient constraint’s Lock Output attribute is off, you can change the orientation of the constrained object without having to rotate the driver object.

When a constrained object’s Lock Output attribute is on, you can only manipulate its constrained channels by transforming its driver object. When a constrained object’s Lock Output attribute is off, you can directly manipulate its constrained channels, without having to transform its driver object.

Note
The Animation Blending preferences affect the default state of the Lock Output attribute.
Offset: Specifies an offset position for the constrained object relative to the target point. Note that the target point is the position of the target object’s rotate pivot, or the average position of the rotate pivots of the target objects. Default values are all 0.

Interp Type

Sets the rotation interpolation type for the constraint. Interp Type is relevant only when the constrained object has multiple targets.

Average: Averages rotation between the constrained object and its targets.
Shortest: Finds the shortest path between rotations from the constrained object to its targets using quaternion interpolation.
Longest: Finds the longest path between rotations from the constrained object to its targets using quaternion interpolation. This path is in the opposite direction from Shortest.

Tip
Set keyframes between Shortest and Longest rotation interpolation to prevent flipping.
No Flip: No Flip caches the current rotation onto the constrained object. Once you select No Flip, you must click the Cache button to create the cache.

Cache

Cache appears in the Interp Type menu field when there is cached interpolation on the constrained object.

Create: Caches the current rotation interpolation onto the constrained object. Caching reduces the chance of flipping. Only available when you select No Flip.
Delete: Deletes the current rotation interpolation cache from the constrained object. Only available when Cache appears in the Interp Type menu field.

Constraint Rotate: Informs you of the constrained object’s current orientation.
