Controls how the face-tracking pipeline extrapolates animation data between camera frames on the [`TrackerLodController`](https://rapi.sleaze.dev/classes/TrackerLodController.md).

## Items

| Name | Value | Description |
| --- | --- | --- |
| `ForceDisabled` | 0 | Disables all extrapolation so that facial animation updates only when a new camera frame is processed. |
| `ExtrapolateFacsAndPose` | 1 | Extrapolates both FACS blend-shape values and head-pose data between camera frames. |
| `ExtrapolateFacsOnly` | 2 | Extrapolates only FACS blend-shape values between camera frames, leaving head-pose data unchanged. |
| `Auto` | 3 | Lets the [`TrackerLodController`](https://rapi.sleaze.dev/classes/TrackerLodController.md) automatically select the extrapolation strategy based on current performance conditions. |
