Armature Modifier

The Armature Modifier is used for building skeletal systems for animating the poses of characters and anything else which needs to be posed.

By adding an armature to an object, this object can be deformed accurately so that geometry does not have to be animated by hand.

The Armature modifier.


The name of the armature object used by this modifier.

Vertex Group

The name of a vertex group of the object, the weights of which will be used to determine the influence of this Armature Modifier’s result when mixing it with the results from other Armature ones.

Only meaningful when having at least two of these modifiers on the same object, with Multi Modifier activated.

Invert <->

Inverts the influence set by the vertex group defined in previous setting (i.e. reverses the weight values of this group).

Bind to
Vertex Groups

When enabled, bones of a given name will deform points which belong to vertex groups of the same name. E.g. a bone named “forearm”, will only affect the points in the “forearm” vertex group.

The influence of one bone on a given point is controlled by the weight of this point in the relevant group. A much more precise method than Bone Envelopes, but also generally longer to set up.

Bone Envelopes

When enabled, bones will deform points or control points near them, defined by each bone’s envelope radius and distance. Enable/Disable bone envelopes defining the deformation (i.e. bones deform points in their neighborhood).
