extremities. Adjust the Smoothing Bias control
to distribute the chain’s rotation towards the

Bend Links Mode—This mode can b e used to
rotate multiple links of a chain without ha ving to
select all of them beforehand. Bend Links Mode
transfers the rotation of one link to the other links,
following a natural curvature.

Twist Individual Mode—Similar to Bend Links
Mode,thismodeallowsaselectedchainlinkto
be rotated in local X without affecting its parent
or child. The chain therefore maintains its shape
while the individual link is adjusted.
Note: Using Twist Individual Mode in Auto Key
mode or setting a key after twisting results in keys
on all the links of the selected chain. See Separate
Tracks (page 2–962) for further details.
Smooth Twis t Mode—This mode takes into
account the orientation in local X of the chain’s
first and last links in order to distribute the
rotation of the other links. This results in a smooth
rotation between every chain link. The rotation
distribution can be set by adjusting the Smoothing
Bias control or by rotating either the first or last
link of the chain .
Smoothing B i as—Sets the rotation distribution
based on a va lue between 0.0 and 1.0. 0.0 biases
towards the first link and 1.0 towards the las t
link of the chain. The chain’s smoothness can
be interactively set by dragging the bias setting
between those 2 values.
Zer o Twi st —Resets every chain link ’s rotation
to 0 in local X based on the current orientation
of the chain’s parent. This does not change the
current shape of the chain.
Zer o A l l — Resets every chain link ’s rotation
to 0 in all axes based on the current orientation of
the chain’s parent. This adjusts the current sh ape
of the chain so it becomes parallel to the biped.

Tools in the Key Info rollout allow you to do the
following:
• Find the next or previous key for the selected
biped body part.

• Change Tension, Continuity, and Bias for a key
and display tr ajectories.
• Adjust biped dynamics.
• Set planted, sliding, or free keys.
