Fine Tuning Morph Strength

The ARKit Tuner maps 52 ARKit signals to a CC3+ character's default 75 morphs (or 160+ if using CC4 Extended morphs). You can adjust and correct the output generated by the ARKit Tuner with the Face Tuner Mapper, which builds upon this mapping allowing independent fine-tuning of each individual morph (from 75 to 160+).

Follow the steps below to fine tune the ARKit tuning results.

1. Right-click on the empty area of the Speech graph, and select ACE-A2F > A2F Control > Face Tuner Mapper from the context menu.
   
2. The Face Tuner Mapper node is created.
   
3. Select the node to show the available morphs on the character in the Parameters section.
   
   The tuning parameters include:
   • Offset: Adds or subtracts a fixed value from the ARKit Tuner’s output for precise result adjustments.
   • Scale: Multiplies the output of the ARKit Tuner by a user-defined ratio to intensify or reduce the strength of each morph.
   * When the character changes, click the Reload Morphs button to load available morphs for the new character.
4. Click on Export Face Tuner Mapper to save the tuning configurations as a preset in JSON format. You can then import the saved preset by clicking the Load Face Tuner Mapper button anytime.
5. Connect the node to the Face Tuner Mapper input of the Audio2Face node.
6. Enable and map the Emotions to the ones of LLM.
