Child Of Constraint¶
The Child Of constraint transforms an object or bone as though it were a child of another object or bone.
The main advantage over a regular parent-child relationship is that the constraint has an animatable Influence, which makes it possible to switch to different parents over time.
This same Influence can also be used to mix multiple Child Of constraints and create a weighted average between multiple parents. However, if those parents are bones, the Armature Constraint may be a better choice.
Note
While this constraint can “parent” a bone to another, it’s not very suited for creating chains of bones. Notably, it can’t emulate connected bones (where the tip of the parent always coincides with the base of the child).
Options¶
Child Of constraint.¶
- Target
The parent object or bone.
- Location
The location axes of the child to affect.
- Rotation
The rotation axes of the child to affect.
- Scale
The scale axes of the child to affect.
- Set Inverse
If the child’s transform is correct with the constraint disabled but incorrect with the constraint enabled, click this button to fix it.
- Clear Inverse
Tells the constraint that the child’s current transform with the constraint disabled is its correct relative transform. Once the constraint is enabled again, this transform will be applied as an offset to the parent to determine the child’s final transform.
- Influence
How strongly the constraint affects the owner.
