By default, no Character is displayed when YanusLIVE starts. Unreal Engine or Unity Package applications can be launched and closed via buttons, and operate by importing their output into the Character display window.
## Character mode control
* **Character mode** : In [**Settings: Character**](/yanuslive/settings/settings-character.md), the predefined list appears as a dropdown (combo box) for selection.
* **Start** **/ Stop** Button : Starts and stops the Character application.
{% hint style="info" %}
Startup may take a few seconds. On the first run after installation, security prompts might block importing and open a separate window. If this happens, please stop and start the application again.
{% endhint %}
{% hint style="info" %}
Changing Character mode while a Character app is running closes the current app and starts a new one. This may cause slight delays depending on your PC.\
To manage resources, Actor mode stops during this process and restarts automatically once the new app is ready.
{% endhint %}
## Pixel Streaming mode
The Character mode supports Unreal Engine’s Pixel Streaming. In this case, start the Pixel Streaming Server in the Unreal Engine project before starting the application.
