Position/Orientation/Bind to Follow Object (HD Solver) 475
Use Weight to set the relative influence of
multiple follow objects or end effectors, and
thus their priority i n solving the IK solution.
The higher the relative Weight value, the hig her
the priority.
Note: As you drag, a dotted line is drawn from
the pivot point of the selected object to the
cursor. When the cursor is over a valid follo w
object, it changes to a push-pin cursor. Release
to set the follow object. The name of the follow
object wi ll appear in the text area.
To unbind an object:
• Select the object to unbind, and then click
Unbind.
In the text area, the name of the follow object is
replaced with the word "None."
Inter face
Position group
Bind Position—Binds the selected object in the
IK chain to the world (attempts to maintain its
location), or to a follow object, if one has b een
assigned. If a follow object has been assigned, then
the translation of the follow object affects the IK
solution.
Note: This check box has no effect on the HD IK
Solver Position end effectors, which are always
bound to their assigned joints.
Orientation group
Bi nd Ori entation—Binds the selected object in the
hierarchy to the world (attempts to maintain its
orientation), or to a follow object, if one has been
assigned. If a follow object has been assigned,
then t he
rotation of the follow object affects the
IK solution.
Note: This check box has no effect on the HD IK
Solver Rotation end effectors, which are always
bound to their assigned joints.
R—Establishes a relative position offset or rotation
offset between follow object and end effector.
This button has no effect on the HD IK Solver
Posit ion end effectors. They are created on top
of the joint to which they’re assigned, and are
automatically absolute.
If you move the joint away from the end effector,
and want to reset the end effector to an absolute
position, you can delete and then recreate the end
effector.
Axis X/Y/Z—If one of the axes is turned off, the
specified axis is no longer influenced by the follow
object or the HD IK Solver Position end effector.
For example, if you turn off the X axis in the
P osition group, movement of the follow object (or
endeffector)alongtheXaxishasnoeffectonthe
IK solution, but movement along the Y or Z axis
has.
Note: These do not constrain the movement of the
follow object or end effector.
Weight—Sets the influence of the follow object (or
end effector) on its assigned object, and on the rest
of the chain. A setting of 0 turns off the binding.
Using this value you can set the relative influence
