# Settings: Experimental

Settings to enable or disable additional processing along with other configurations.

Changes in this tab take effect instantly upon clicking Apply, regardless of Actor mode status.

### CSV Data File Play

This mode plays video files by loading data from a pre-generated CSV file. It is useful for verifying generated facial data or performing lightweight data transfer tests without running the full Facial Mocap process.

When playing a CSV file, the Actor screen is outlined in green for clear distinction. The Facemesh view is automatically disabled, and neutral calibration values as well as retargeting by the Actor Profile are not applied.

### Neutral Calibration

* **Auto Scale Adjustment in Neutral Calibration**
  * This feature adjusts the scale range using the formula `1 / (1 - neutral_value)` when the neutral value is greater than 0.5, and automatically sets the scale to half of that range.
  * In previous versions (\~v1.6.3), this was always applied in order to compensate for the issue where changes in the corresponding blendShape appeared too subtle.
  * To prevent the side effect of noise amplification, the default setting is disabled upon installation.
* **Apply Eye Direction Neutral Value During Retarge**t
  * This option is not applied during Neutral Calibration.
  * When performing Neutral Calibration using a recorded video, it is recommended to disable this option if there are no front-facing frames.

### Emotional Improvement

An option for enhancing emotional facial expressions. The relevant blendShapes are **CheekSquint** and **NoseSneer**, and a separate pre-calibration factor has been applied in addition to the Actor Profile.

### Sync Eye Movements

An option to determine whether the movements of both eyes should be synchronized or move independently. If the asymmetry between the movements of both eyes exceeds the threshold based on the selected reference eye, their movements will be synchronized.

### Head Rotation

Enable the use of Head Rotation values in LiveLink data

{% hint style="info" %}
A Kalman filter is used for noise filtering, and when the Filter Preset is set to Stable, a median value of 4 might be excessive. It is recommended to increase responsiveness by sliding the control to the left and setting it to around 2.
{% endhint %}

### Font Size

An option to specify the font size of tooltips displayed in the Value and Actor Profile Editor.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.yanusstudio.com/yanuslive/settings/settings-experimental.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
