Maintain Volume Constraint¶
The Maintain Volume constraint limits the volume of a mesh or a bone to a given ratio of its original volume.
The free-scaling axis of the object.
X, Y, Z
Specifies how the constraint handles scaling of the non-free axes.
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.
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.
The bone’s rest volume.
This constraint allows you to choose in which space to evaluate its owner’s transform properties.
