Radius—
Select an envelope cross section, and
useRadiustoresizeit.Inordertoselectacross
sect ion, the Cross Sec tions option in the Select
group must be checked.
You can also click and drag a cross section control
point in a viewport to resize it.
Squash—A squash multiplier for bones that stretch.
This is a single value that reduces or increases the
amount of squash applied to a bone when it is
stretchedwithFreezeLengthoff,andSquashon.
Note: You can set Freeze L ength and Squash in the
Bone Tools dialog (page 1–391) .
Absolute/Relative—This toggle determines how
vertex weights are calculated for vertices between
inner and outer envelopes.
•
Absolute—A vertex must merely fall
inside the brown outer envelope to have 100%
assignment weight to that particular bone.
A vertex falling inside more than one outer
envelope will be assigned multiple weights
summing to 100% based on where it falls in the
gradients of each envelope.
•
Relative—A vertex falling only w ithin an
outer envelope will not receive 100% weighting.
A vertex must either fall inside two or more
outer envelop es whose g r adients sum to 100%
or greater or the vertex must fall within a red
inner envelope to have 100% weight. Any
points within a red inner envelope will be 100%
locked to that b one. Vertices falling within
multiple inner envelopes will receive weighting
distributed over those bones.
Envelope V isibility—Determines the
visibility of u nselected envelopes. Choose a bone
in the list and click Envelope Visibility, then
choose another bone in the list. The first bone
selected remains visible. Use this to work on two
or three envelopes.
Fa lloff Flyouts—Select a falloff curve for the
displayed envelopes. Weight falls off in the area
between the inner and outer envelope boundaries
if envelopes overlap and Absolute is turned on.
Controls here allow you to specify how the falloff
is handled.
Falloff Fast Ou t—Weight falls off quickly.
Falloff Slow Out—Weight falls off slowly.
Falloff Linear—Weight falls off in a linear way.
Falloff S inual—Weight falls off in a sinual way.
Co py—Copies the currently selected envelope
size and shape to memory. Turn on sub-object
Envelopes, choose one bone in the list, click Copy,
then choose another bone in the list and click Paste
to copy an envelope from one bone to another.
Paste commands are on a flyout with the following
options:
Pas te—Pastethecopybuffertothecurrent
selected b one.
Paste to All B ones—Pastes the copy buffer to
all bones in the modifier.
Past e to Mul tipl e B ones—Pastes the copy
buffer to selected bones. A dialog al lows you to
choose the b ones to paste to.
