Step
1
If
you want to be able to rotate the eyes manually, or independently
from each other, after you set up the LookAt or Orientation
Constraint controllers, you'll have to use a List controller.
This is one of the more handy controllers, and you can use it
on Position and Scale, as well as Rotation.
What is does is allow you to combine multiple controllers on one
object. In this case we need it to assign both the automatic animation
type controller we've already went over, and the Euler XYZ
controller so we can take back control of the eyeball when
we want.
First
thing you want to do is go to the Motion Panel and under
the Assign Controller menu, click on Rotation. Then
click the Assign Controller button (the question mark),
and select Rotation List.

Step
2
Now
if you expand the Rotation Controllers tree you'll see a
new controller slot labeled Available.
|
|
Step
3
Highlight
Available, click on the Assign Controller button, and
select Euler XYZ from the list. Now you'll see the Euler
XYZ controller in your Rotation drop down list, along
with whatever controller you applied previously. Plus, the Available
slot is still there so you could add more controllers if you
wanted.

Step
4
Now,
depending on which order you've added your controllers, you might
not be able to rotate the eye manually yet. What you need to do
is tell Max which controller is the active one. Scroll down the
Motion Panel until you get to the Rotation List section.
Click on Euler XYZ and then click Set Active.
|
|
Step
5
Now
you can rotate the eye however you want, and still be able to have
it automatically rotate with the helper object you've already set
up.

The
List Controller is a necessary component to many character rig setups.
You'll usually apply it before applying any custom controllers so that
you can always go back and manually move a bone or other part of the body.
Now would be a good time to investigate the other controllers available
and see what they do. I'll go over one in particular next that can come
in handy in certain, specific situations.
