# The Master Component: FaceSync Controller

The `FaceSyncController` is the "brain" of your character. It unifies all facial features into one clean custom Inspector.

#### Modules Breakdown:

* 🫦 LipSync (Speech): Set your `Target Mesh` (the SkinnedMeshRenderer with facial blendshapes) and assign a `VisemeMappingProfile`. You can set the mode to `Playback` (for Timeline/Scripts) or `LiveMicrophone`. Includes distance-based LOD culling to save performance.
* 👁️ Eyes & Blinking: Automatically finds your Blink and Look blendshapes. Adjust `Min/Max Blink Interval` and enable `Saccadic` and `Micro Jitter` for realistic eye darts.
* 💆 Head & Neck Motion: Assign the Head and Neck bones. The controller uses Perlin noise driven by voice energy to move the head naturally while speaking.
