Bias Displaces the pivot point about which vertices are bent. Bias pushes the
effect along the spline toward one side of the joint or the other. The default
value of 0.5 centers the bend at the joint. Values lower than 0.5 move the
pivot onto the child link. At 0.0, the bend effect is limited to the selected link.
Range=0.0 to 1.0. Default=0.5.
Twist group
Twist parameters control the way the skin deforms when a joint rotates along
its length, as in turning a doorknob.
Use Twist for Rigid When on, twist is used for rigid as well as deformable
envelopes. Default=off.
Turn off for the rigid envelope for a character's head: the head should not
twist along the length of the link. You might want to turn this on for the
forearm or upper-arm link if you’re using rigid envelopes.
Tension Values lower than 1.0 concentrate the effect closer to the joint. Values
higher than 1.0 move the effect away from the joint. Range=0.0 to 2.0.
Default=1.0.
Bias Shifts the distribution of the twist from one side of the joint to the other.
The default value of 0.5 twists the selected link and the child link equally.
Values greater than 0.5 shift the twist to the child link. Range= 0.0 to 1.0.
Default=0.5
