This is a tutorial setting up a Facial rig Jason Osipa
style within Max 7. I strongly advise everyone to purchase
the book ?Stop
Staring? by Jason Osipa. It goes over a rather
innovative approach to lip synching. It also goes over
modeling and edge loops for good lip synching deformation.
Even though the book is for Maya the principles travel
across all major 3d packages.
I used the parametric head creator by Bruce Forel.
It is a great script for people to begin modeling heads.
I dont personally use the script, but I found it very
helpful for the purpose of demonstrating this tutorial.
Check out his script

Things you will need before you start: |
 |
First you will need a head with the
morpher modifier already on it and hopefully a couple
of targets already loaded into morpher?at least
4 so you can see the real benefits of the rig |
|
Here is a file the has 4 morph targets set up so you
can test out the exercise. The morph targets are:
Right_smirk - Left_smirk - Mouth_open - Mouth_pout

Second Rig Tools script. My friend
?Phatdaddy? (Walter Osborn) wrote a script
that automates the controller creation for the face rig.
The rig controller is based off ?Rigman? (Alvaro
Sanint) controller |

This tutorial is also possible to do with the Joystick
Manipulator by Borislav Petrov (not nescassary for this
tutorial) |

|
Open your scene with the morpher head in it |
|
1a. Click on Rig Tools and type in ?Mouth?
in the name slot under ? Parameters ? |
 |
|
Pay close attention to the default Units. The Width
and Height are set to 5 units. This will
come up later on. |
|
Click in the front viewport to create it. |
2a. Go to the ? Animation ? menu and select
? Reaction Manager ? |
 |
|
3a. In the reaction window click the ?
Add Master ? button in the top left. |
 |
|
4a. While in ? Add Master ?
mode, click on the controller circle ? Mouth_circ
? Then go to Tranform ? FK Sub_control ?
Position ? X Position |
 |
|
This will add the master ( Mouth_circ / X Position )
in the ? Reactions ? |
|
5a. Now click on the button ? Add Slave ?
it should be next to the ? Add Master ? button. |
 |
|
6a. While still in ? Add Slave ? mode, select
the main head with morpher applied. Go to
Modified
Object ? Morpher ? [1] left_smirk
|
 |
|
Notice how the value of the ? State01 ?
and the ?left_smirk? target value are both
set to 0.00 |
|
 |
|
7a. Double click on the value of the State01
. Set the Value to 2.5. Remember the
area of the square was 5 units, so the
distance from the middle to any side will be half. |
|
8a. Double click the value of the left_smirk target
and set it to 100.
This means that whenever you move the controller to its
full extent, it will set the corresponding morph target
to 100
|
 |
|
Now you will create a neautral state. |
9a. In the states panel, click on ? Create State
?. |
 |
|
10a. Set the value of both the new state (State02) and
the target (left_smirk) to 0 |
 |
|
You have now linked morpher to a controller. Repeat
steps 3a ? 10a linking the master to the appropriate
axis direction you will move the controller and using
the morpher head as the slave corresponding to the respective
morph target you would like to call.
Note: remember that the state value going up and right
will always be a positive value and negative if its going
left and down.
This is an example of a completed setup for the x axis.
Notice the negative values for the right smirk....this
will be assigned to the controllers left position or the
"directors" left

I hope this tutorial has been helpful. I advise you
to go over this tutorial several time to fully grasp
the use of the "Reaction Manager". It's an
extremely powerful tool.
