parentConstraint

In the Attribute Editor, you can view or edit the characteristics of the parent constraint node. To edit this node, you must first select its name in the Outliner or its tab in the Attribute Editor. If you selected it in the Outliner, go to Window > Attribute Editor or use the shortcut

+a to view its attributes. For more information, see General constraint node attributes.

The following section describes the attributes specific to the Parent constraint node (parentConstraint).

Parent Constraint Attributes

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

NoteThe Animation Blending preferences affect the default state of the Lock Output attribute.

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.
No Flip and Cache: 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 appears in the Interp Type menu field when there is cached interpolation on the constrained object.
Cache Create button: Caches the current rotation interpolation onto the constrained object and creates an animation curve for the current rotation interpolation on the constraint’s node. Caching reduces the chance of flipping. Only available when you select No Flip.
Cache Delete button: Deletes the current rotation interpolation cache from the constrained object. Only available when Cache appears in the Interp Type menu field.

Constraint Translate: Displays the constrained object’s current position. This value can be useful when specifying the Offset Translate value. This field is read-only.
Constraint Rotate: Displays the constrained object’s current rotation. This value can be useful when specifying the Offset Rotate value. This field is read-only.
Enable Rest Position: See Rest Position attributes.
Rest Translate: See Rest Position attributes.
Rest Rotate: See Rest Position attributes.
