Main Rig System

Facial Basics – Primary Controls

This section contains the most essential facial controls for animating natural expressions and responses. These controllers are positioned directly over facial features and provide intuitive manipulation.

• Eyebrows (Inner/Outer): Raise or lower each section independently to shape nuanced expressions.

• Eyes: Open and close each eyelid separately or simultaneously for blinking and squinting actions.

• Pupils: Dilate or contract each pupil individually.

• Nose: Joystick control for nostril flare and upper nose squint. The effect changes depending on the direction of the movement (up/down, left/right).

• Cheeks: Inflate/deflate cheek volume and trigger cheek squints.

• Ears: Move ears vertically for added secondary motion or stylized effects.

• Upper / Lower Lip: Raise or lower the lips either centrally or by side to create asymmetrical or symmetrical gestures.

• Mouth Corners: Push or pull the corners of the mouth for expressions like smiles, stretches, or dimples.

• Jaw Controls: Open the jaw normally or in wide mode, close the mouth even when the jaw is open, or apply circular motion to simulate speaking or chewing.

• Neck Tension: Adds muscular tension along the neck to simulate effort, emotion, or stylized motion.

These controls serve as the base layer for expressive animation.

Eye Gaze Controls

This module lets you control where the character is looking with precision and flexibility.

• Individual Eye Controls: Two circular controllers allow you to independently animate each eyeball’s gaze direction. Ideal for stylized expressions, divergent gaze, or fine-tuned adjustments during close-ups.

• Global Eye Control: A centered rectangular controller drives both eyes simultaneously, keeping them synchronized when needed—for natural eye contact or focal tracking.

All eye movements respect anatomical constraints and are dampened to avoid jittery results.

Facial Deformers

This secondary layer of facial controllers is designed for fine-tuning expressions and deformation correction. It complements the main facial widget by giving you direct access to subtle shape refinements that may be required during extreme poses or close-up shots.

• Micro Deformers: These smaller circular handles scattered around the face allow you to make delicate adjustments to cheeks, lips, eyelids, and brow shapes—ideal for polishing expressions or fixing mesh intersections.

• Tooth Controllers: The two dark circular deformers inside the mouth are used to reposition the upper and lower teeth independently. Useful for correcting bite alignment during exaggerated phonemes or stylized animations.

This layer remains non-intrusive and can be toggled via the custom panel for optimal viewport clarity.

Tongue Deformers

In addition to the joystick-based tongue controls, OMNIA includes dedicated deformers for the tongue geometry. These allow for precise sculpting of tongue shape during phoneme articulation, extreme motion, or stylized expressions.

• Each deformer can move, scale, or rotate parts of the tongue tip and body to fine-tune silhouettes from various camera angles.

• Especially useful when blending visemes, yelling, or creating exaggerated cartoon-style motion.

• They remain active even during rig-based animation and do not conflict with the main tongue joystick logic.

Torso, Neck, and Head

Here you'll find controllers organized to manipulate the spine, chest, neck, and head. Use R to rotate as needed.

• Head Rotation: rotates the head without affecting the torso.

• Neck Rotation: allows subtler neck movement.

• Shoulder Controls: raise, lower or rotate the shoulders.

• Torso Upper / Lower: rotates the chest or hips.

• Torso Move: moves the entire torso.

In IK mode, the hands and feet will stay in place even as the torso moves.

Torso Tweaks

These tweaks are located between the neck and hips. They let you add smoothness and natural motion to spine rotations. Typically used with R to rotate.

They support the main controllers and help refine pose aesthetics.

IK Controllers

For arms:

• Wrist: red octagon to move the hand.

• Bicep: red circle to orient the elbow.

For legs:

• Ankle: red octagon that moves the whole leg.

• Thigh: circle to orient the knee.

• Heel: small circle behind the foot to lift the heel.

• Toes: moves them all together.

IK is ideal when limbs are grounded or must remain fixed while the body moves.

FK Controllers

FK gives you direct control over the rotation of each part.

For arms:

• Wrist (green circle), Forearm (octagon), Upper arm (shoulder circle).

For legs:

• Thigh, knee, ankle and toes each have their respective green controllers.

FK is very useful when limbs need to follow the torso naturally.

Limb Tweaks

These blue controllers allow fine twist control for arms and legs.

• Arms: tweaks for shoulder, bicep, elbow, forearm, and wrist.

• Legs: tweaks for hip, thigh, knee, and calf.

They don't affect the overall structure but improve pose accuracy, especially in complex animations.
