The Auto Termination controls temporarily assign terminators a specific
number of links up the hierarchical chain from the selected object. This only
works with Interactive IK; it does not work with applied IK or with IK solvers.
Procedures
To use auto termination:
1 In the Auto Termination rollout, turn on Auto Termination.
2 Enter a value in the # of Links Up field.
Turn on the IK button on the toolbar.
3 Select any object in an IK chain to move or rotate.
Interface
Interactive IK Auto Termination Turns on the auto termination feature.
# of Links Up Specifies how far up the chain the termination is applied.
For example, if you set this to 5, when you move any object in the hierarchy,
the object that's five links up the chain from the object you're adjusting acts
as a terminator. If you select a different object in the hierarchy, termination
is switched to whichever object is five links up the chain from the newly
selected object.
A setting of 1 simply locks the hierarchy, since it terminates the joint just
beyond the currently selected object.
Link Info
Make a selection. > Hierarchy panel > Link Info button
This part of the Hierarchy panel contains two rollouts. The Locks rollout has
controls to restrict the movement of objects in a particular axis. The Inherit
rollout has controls to limit the transforms that a child inherits from its parent
object.
