Armature Constraint

Armature is the constraint version of the Armature Modifier, exactly reproducing the weight-blended bone transformations and applying it to its owner orientation. It can be used like a variant of the Child Of constraint that can handle multiple parents at once, but requires all of them to be bones.

Merknad

Unlike the Armature modifier, the constraint does not take the Deform checkbox of bones into account, and can use any bone as target.

Options

Armature constraint.

Preserve Volume

Like the matching option of the modifier, it enables the use of quaternions for preserving the volume of the object during deformation.

Use Envelopes

To approximate envelope-only behavior of the modifier, add all relevant bones with weight 1.0 and enable this option.

Merknad

Unlike the modifier, the constraint always requires explicitly listing all of its target bones with associated weights. This option merely enables envelopes for all bones, as if they had Envelope Multiply enabled.

Use Current Location

Only for constraints on bones: Instead of using the rest location, use the current location of the owner bone to compute envelope weights or binding to B-Bone segments.

With envelope weights, this can be used to change the active «parent» bone of the owner bone dependent on its location. For non-bones this mode is always active, because they don’t have a rest location.

Add Target Bone

This button adds a new empty entry at the end of the target list.

Normalize Weights

This button normalizes all weight values in the target list so that they add up to 1.0.

Influence

Controls the percentage of affect the constraint has on the object. See common constraint properties for more information.

Bones

This specifies the list of bones used by the constraint to deform its owner. Each target bone has the following input fields and controls:

Target

Unlike the modifier, the constraint can use bones coming from different armatures at the same time. See common constraint properties for more information.

Sub-target

Name of the target bone.

(Remove Target)

Removes the entry from the target list.

Weight

Weight associated with the bone, equivalent to vertex groups in the modifier.
