The offset of the volume with respect to the anchor's pivot as a Vector3.
The offset is mostly zero, as most objects have the anchor's pivot aligned with the top face of the volume.The offset is not zero in cases where the anchor's pivot point is aligned with another element, such as the seated area for a couch, defined as a plane.The Offset is provided in the local coordinate space of the children.
