Link Sub-Object
Select an object that has the Physique modifier applied
to it. > M od ify panel > Link sub-object level
Use parameters at the Link sub-object level to
change how deformation around joints occurs.
When a joint in the skeleton bends or rotates,
Physique, by default, deforms vertices uniformly
on either side of a joint. You can change these
defaults by u s ing the tools at the Link sub-object
level. F or example, you can adjust the amount of
skin sliding that occurs along a limb as the limb
bends, or change the angle of the crease between
the upper arm and chest.
The Physique Deformation Spline
The deformation spline displays as a yellow curve that runs
through the mesh.
Like a spline object, the deformation spline created
by Physique is a continuous curve through several
points. While a spline objec t runs continuously
from vertex to vertex, the deformation spline is
a smooth curve running from joint to joint. The
Bend, Bias, and Tension spinners can change t he
shape of the curve, much as you can rotate or scale
thehandlesatasplinevertex.
The deformation spline also takes into
consideration twisting and scaling of the skeleto n’s
links. At the Link sub-object level, you take
control of the behavior of the deformation spline,
and subsequently gain full control of the skin’s
behavior relative to the skeleton’s movement.
