Partial Ble nding on all the deformable envelopes for
the bones in this character’s jaw allows smooth mesh
deformation when the bones are moved.
Envelope Parameters group
Envelope ty pe drop-down li st—Sho ws the type of
the selected envelope. If the link has both a rigid
and a deformable envelope, you can use this list
to choose which envelope’s parameters you are
adjusting.
Strength—Changes the strength of the envelopes.
Range=0.0 to 100.0. Default=1.0.
Strength applies to both the inner and outer
envelope bounds.
Used primarily for areas where envelopes overlap,

other.
Fa lloff—Changes the rate of falloff between the
inner and outer bounds of an envelope. This
is a Bezier curve function. Range=0.0 to 1.0.
Default=0.1.
Vertices within the inner bound are fully
influenced (weight=1.0) and those beyond the
outer bound get no influence from the link
(weight=0.0). Falloff determines the r ate at which
the influence falls off from 1.0 to 0.0.
The Inner, Outer , and Both buttons determine
whether the controls that follow, Radial Scale,
Parent Overlap, and C hild Overlap, apply to
the envelope ’s inner bound, its outer bound, or
both at once. First, use the buttons to choose
which bounds to adjust, then change values in t he
spinners.
Inner—Tur n on to chan ge t he va lues of the in ner
bound.
Outer —Turn on to change the values of the outer
bound.
Both—Tu r n on to change the value s for b oth inne r
and outer b ounds at the same time.
When Both is selec ted, the values displayed for
Radial Scale and Parent and Child O verlap reflect
the values for the
inner
bound.
Radial Scale—Radially scales the envelope bounds.
Range=0.0 to 100.0. Default=1.0.
