You
can view or edit attributes of the parent constraint node in the Attribute Editor.
To view parentConstraint attributes, do one of the following:
- Select a parent-constrained object and
switch to the parent constraint tab in the Attribute
Editor.
- Select the constraint in the Outliner and
press +a (or
select Window > Attribute Editor)
to view attributes.
The following section
describes the attributes specific to the Parent constraint
node (parentConstraint). See also
General constraint node attributes.
Parent Constraint Target
Offsets
These attributes let
you modify the offset between the constrained object and the target
object(s). If you have multiple target objects, each object is listed with
individual Translate and Rotate offset
values. See
Modify parent constraint offsets.
- Translate
-
Enter XYZ translation
values for the offset between the target object and the constrained object.
- Rotate
-
Enter XYZ rotation values
for the offset between the target object and the constrained object.
- Update
-
If you have moved the
constrained or target object(s) in the scene, click to update the
target offset values to the current object location.
- Key
-
Click to key the target
offset values at the current time.
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

- Rest Translate
