Bias—
Shifts the effect of radia l scaling. At the
default value of 0.5, scaling affects both the selected
linkandthechildlink.Valueslowerthan0.5shift
the s caling effect onto the selected link, and values
greater than 0.5 shift scaling onto the child link. At
0.0, expansion and contraction are limited to the
selected link. At 1.0, exp ansion and contraction
arelimitedtothechildlink. Range=0.0to1.0.
Default=0.5.
Link Scale—Scalestheentirelinkradially,
independent of the effect of any cross sections. At
1.0, the link is “actual size” and this setting has no
effect. Other va lues increase or decrease the radial
scale of t he link. Range=0.0 to 10.0. Default=1.0.
CS Amplitude—Cross sec tion amplitude has no
effectunlessthelinkhasbulgeanglecrosssections.
At 0.0, cross sec tion deformation is turned off.
Values greater than 1.0, up to the maximum
of 10.0, exaggerate the effect of cross sec tions.
Default=1.0.
Stretch—When on, preserves the volume of the
link’s skin when the length of the link changes.
The effect is similar to stretching or squeezing a
material that is only par tly elastic, such as a tough
rubber hose. Default=off.
Above: Stretch is turned on.
Below: St retch is turned off.
As the bones change in length, the mesh expands and
contract s when Stretch is on.
Breathe—When on, scaling a skeleton node
changes the radial scale of the link’s sk in. When
off, scaling a node has no effect on the scale of the
skin. Default=off.
Above: Breathe is turned on: the mesh is scaled as the
object is scaled.
Below B reathe is tur n e d off: object scaling doesn’t effect
the mesh.
The linked objects are shown in white. The lowest, largest
object is the one that has been scaled. These linked objects
were used as the hierarchy for Physique.
