Genesis 9 (DAZ3D) Import Guide

This guide summarizes the known issues with DAZ3D Genesis 9 characters imported into Unity and the recommended Crystal LipSync setup.

Important: This is not a Crystal LipSync defect. The eye/blendshape reliability problems described here are caused by DAZ3D Genesis 9 export/import behavior in Unity.

Why Genesis 9 needs special handling

Some Genesis 9 exports include blendshape data that is inconsistent or unreliable in Unity for eye movement and facial weighting. In practice, this can cause:

• Eye look blendshapes that do not animate correctly or consistently

• Combined eye-look blendshapes that appear mapped but do not produce reliable motion

• Overdriven mouth motion if viseme weights are left at full strength

These limitations originate in the DAZ3D-to-Unity pipeline (exported morph behavior and naming/data consistency), not in Crystal LipSync's runtime logic.

Because of this, the recommended approach for Genesis 9 is to use bone rotation for eye movement and conservative profile values for lip/jaw motion.

Recommended Eye Blink / Eye Movement setup (Genesis 9)

Use this setup in CrystalEyeBlink:

• Force Bone Rotation = On

• Look Mesh = None

• Eye Movement blendshape mapping:

  • Look Up (Left Eye) = None

  • Look Up (Right Eye) = None

  • Look Down (Left Eye) = None

  • Look Down (Right Eye) = None

  • Look Left (Left Eye) = None

  • Look Left (Right Eye) = None

  • Look Right (Left Eye) = None

  • Look Right (Right Eye) = None

  • Look Up (Both) = None

  • Look Down (Both) = None

  • Look Left (Both) = None

  • Look Right (Both) = None

Notes:

• Brow Sync still uses the Target Mesh (body mesh), not the Look Mesh.

• Eye movement is driven by left/right eye bones, which avoids the Genesis 9 look-blendshape issues.

Recommended Blendshape Profile values (Genesis 9)

For smoother and less exaggerated lip motion on Genesis 9, use lower vowel strengths in your profile:

• A = 0.3

• E = 0.3

• I = 0.3

• O = 0.3

• U = 0.3

This is a practical baseline; adjust slightly per character if needed.

Recommended jaw-bone value (Genesis 9)

For jaw-bone-driven mouth motion, use a conservative max jaw angle around:

• Jaw Bone Max Angle ≈ 4°

This generally avoids over-rotation on Genesis 9 imports while preserving articulation.

Setup Wizard behavior (Genesis 9)

When using Crystal LipSync Setup Wizard with Genesis 9:

• Eye movement is configured for bone-driven mode

• Look blendshape mapping is left empty (None)

• Brow sync remains blendshape-based on the Target Mesh

Quick validation checklist

After setup, verify:

• Eyes follow movement targets via bone rotation (even with all look blendshape slots at None)

• No combined look blendshape slots are used

• Brows animate from Target Mesh mappings

• Mouth animation is not overdriven with vowel weights at 0.3

• Jaw motion looks natural around a 4° max angle
