CA_Mouth

Creates a cartoon jaw and lips. Features include lips seal, zipper, auto volume, thickness, upper lip push, etc.

Guides:

• ‘Jaw’ – Jaw pivot position, usually positioned in the middle of the head on the X axis and slightly in front of and below the ears on the Y and Z axes.
  
• ‘L/R_mouth_corner’ – Place at the lip corners and align with the lips.
• ‘M_upper_lip’, ‘M_lower_lip’ – Position at the center of the upper lip or lower lip.
• ‘L/R_upper_lip_minor’, ‘L/R_lower_lip_minor’ – Placed evenly between middle and corner guides on the lips.
• ‘L/R_mouth_shape_A’, ‘L/R_mouth_shape_B’ – Place these guides past the lips and inside the cheek. A curve will be driven by them, and the corner ctrls will move along that curve.

Guide’s Important Notes:

• The ‘Mirror Mouth Guides’ button makes the right side guides mirror the left side.
  So with a symmetrical character, you only need to place the guides on the left side.
  Using this button in ‘Solo Mode’ will mirror the guides in world space.
• Both upper and lower guides display two curves; the lips skinning joints will be created on those curves. Ensure the curves are on the edges of the lips that are closest to each other.
  
• The guides also drive a thinner curve and this curve controls the movement of the corner ctrls.

Attributes:

1. ‘Mirror Mouth Guides’ – This button positions the right side guides in a mirror image of the left side.
   In ‘Solo Mode’, they will be mirrored in world space.
2. ‘Ctrls Scale’ – Scale all the node ctrls. Note that the attachments ‘Ctrls Settings’ and ‘CtrlsShape’ will override this. 
   [As of version 1.06.03]  ‘Update’ button to change the ctrls size without requiring a rebuild. [Video] 
3. ‘Ctrls Offset Position’ – Offset of lips ctrls for when the ctrls are hidden inside the lips mesh.
4. ‘Jaw Ctrl Offset’ – Offsets the jaw ctrl relative to its pivot. Use this attribute to position the ‘jaw_ctrl’ under the chin.
   
5. ‘Lips Skinning Joints’ – The number of skinning joints per lip, not including corner joints.
6. ‘Lips Bias’ – Use this to control how much the lips move with ‘M_upper/lower_lip_ctrl’.
   
   value of 1.5
   
   value of 1.0
   
7. ‘Create Roll’ – All minor and mid controls will have the ‘Roll’ and ‘Roll loc Vis’ attributes, which allow them to be rotated from a different position. The ‘Roll Loc Vis’ attribute will display a locator that controls from where the roll rotates.
   
   (roll offset positions) 
8. ‘Upper Roll Offset’, ‘Lower Roll Offset’ – The initial roll offset position from the ctrls. In other words, translation values of the roll locators.
9. ‘Upper Lip Push’ – The lower lip will push the upper lip when they collide. Has an on/off attribute on ‘M_upper_lip_ctrl’.
   
10. ‘Micro Ctrls’ – Add a ctrl for every lip skinning joint.

Connections:

• ‘Root Input’ – Drives the whole node, usually driven by the head.
• ‘Head Output’ – An output at the ‘Root Input’ usually drives the upper teeth.
• ‘Jaw Output’ – An output at the jaw joint usually drives the lower teeth.
