Maintain Volume Constraint

The Maintain Volume constraint limits the volume of a mesh or a bone to a given ratio of its original volume.

Options

Free

The free-scaling axis of the object.

X, Y, Z

Mode

Specifies how the constraint handles scaling of the non-free axes.

Strict

This mode overrides non-free axis scaling to strictly maintain the specified volume. Only the ratio between the scale of the non-free axes is passed through.

Uniform

This mode maintains the volume as specified only when the pre-constraint scaling is uniform. Deviations from uniform scaling on non-free axes are passed through.

Single Axis

This mode maintains the volume only when the object is scaled just on its free axis. Any additional non-free axis scaling is passed through.

Volume

The bone’s rest volume.

Space

This constraint allows you to choose in which space to evaluate its owner’s transform properties.
