Estimated building time - under 20 mins

 

1. Drag and Drop Eye module

after drop, you will see like this image with target geos

Drag and Drop → Define a moduleName by usinghttps://junkilee1982.atlassian.net/wiki/spaces/WM/pages/57409541

 


2. Adjust guide shapes - guide set up

  1. CHead1_CMouth:AllCtrlGuide_placer

  2. guide setup

shape By using [translate]
CHead1_CMouth:LipGuideRow_<index>
CHead1_CMouth:LipGuideColume_<index>

Drivers will slide on the guides that it will implement movements based on anatomy.
Lips will move based on green line for instance

Oval shape will implement the drop& rotate hybrid kinematic based on the real anatomy when jaw opens

 

 

Like in the image above, Lips guide has to wrap closely on the jaw guide.

 

3. Place all placers

  1. lips

 

I recommend to have same U values for all
CHead1_CMouth:UpLip_<index>
It will make better performance, but It is not necessary.

 

2. cheeks

 

 

 

3. Lip Puffs and Roll

For CHead1_CMouth:<Side>LipRoll, you can add rotate values to get more rolling behavior.

 

 

4. Animation Mode

  1. animation mode

2. you will get above geos if you build one mouth module.

 

 

 

5. Painting weights

Before painting!

In this example, I applied a DeltaMush on MouthHead_01_frtDef to get smooth.

And “CHead1_” is missing in Handling Weights UI, please consider it

Tips
You can simply copy weight from L to CHead1_CMouth:R_LowCheek_01_wire
And mirror it self than remove left weights on CHead1_CMouth:R_LowCheek_01_wire

How to copy and paste : DeformerMan

5.

 

All drivers slide on the tangent of the guide based.
It makes natural and realistic movement.
Animators can take an advantage of moving only two attributes, it will be handy to adjust animCurves.

6.

 

UpLip and LowLip weights + Jaw weights make the performance above.
DO NOT OVERWRAP each weights.

 

 

 

 

After all painting job done,

Let’s check what you have done so far,
Hide all your <ModuleType>Def_01_geos group node, and show Face_GEOs.
Move around any _Ctrls to check your face rig performance.

If you are not satisficed,

it is free of going for the placing mode to fix pivots or shapes of guides.
Your rigs will be never broken.

or

Modify weights in animation mode
