is an envelope that istoo small to surround, and thereby influence, certain
vertices.
This can happen because your biped character misaligns slightly with the
mesh, or the link lengths used to create envelopes with unbounded bones
systems links were insufficient to surround all vertices attached to the link.
Another potential source of problems is overlapping inner bounds. This can
sometimes create too strong a deformation at the joint.
You'll note problems with vertices as you preview motion. It sometimes looks
like vertices got left behind when the link they were supposed to be attached
to moves in 3D space. In fact, that's just what is happening: they weren't
assigned to any link at all, and remain where they were at the initial skeletal
pose: the pose of the mesh and its skeleton at the time Physique was applied
and initialized.
The other case would be vertices being moved too much, resulting in a dent
in the mesh. You'd fix this by decreasing the overlap of the envelopes affecting
a joint.
