Auto Termination Rollout (Interactive IK) 481
Interactive IK —
Allows for IK manipulation of
hierarchies without applying an IK Solver or using
afollowobject.
Apply IK—Calculates the IK solution for each
frame of the animation and create s transform
keysforeveryobjectintheIKchain.Abargraph
appears on the prompt line to indicate progress
of the calculations.
ApplyOnlyToKeys—Solves the IK solution for
keyframe s that already exist for one of the end
effectors.
Update V iewpor t s—Views the progress of Apply IK
frame by fra me in the viewports.
Clear Keys —Removes all move and rotate keys
from the selected IK chain before applying IK.
Start/End—S ets the range of frames to calculate the
applied IK solution. The default settings for Apply
IK ca lculates the IK solution for every frame of the
active time segment.
Auto Termination R ollout
(Inter a ctive I K )

Termination rollout
The Auto Termination controls temporarily assign
terminators a specific number of links up the
hierarchical chain from the selected object. This

with applied IK or with IK solvers.
Procedure
To us e a uto termination:
1.
In the Auto Termination rollout, turn on A uto
Te r m i n a t i on .
2. Enter a value in the # of Links Up field.
TurnontheIKbuttononthetoolbar.
3. Select any object in an IK chain to move or
rotate.
Interfa ce
Interactive IK Auto Termination—Turns on the auto
termination feature.
#ofLinksUp—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.
