  1. Prepare Model Assets

    Assets provided by the model creator may include a model folder containing model3.json or an LPK file.

    Type Description
    A model folder containing xxx.model3.json Can be freely edited in EX Studio
    xxx.lpk file Packaged model file, cannot be freely edited

  2. Use the Live2D Editor to Add EX-Related Configurations

    Refer to Live2D Editor - Tutorial.

    Configuration Description
    Idle Motions
    Special Motions Triggered by hotkeys
    Expressions Triggered by hotkeys
    Face Parameter Controller Used to bind facial capture data to model parameters
    Hand Parameter Controller Used to bind hand capture data to model parameters

EX Setup

  1. Launch the Application.

  2. Right-click the system tray icon, open the menu, and select Settings > Play. Adjust the settings according to your use case. For live streaming, it is generally recommended to set it to Keep Running.

    Note

    This step applies only to Windows systems. MacOS does not require this setting.

  3. Open the Control Panel, select Model, and import an LPK or Json model. Double-click to load the model.

  4. Open the Control Panel, and set the launch mode to Desktop (Compatible).

    Note

    Desktop (Compatible) is for Windows systems only. On MacOS, select Desktop.

    Difference Between Desktop and Desktop (Compatible)

    • On Windows 7 systems, there may be issues with displaying transparent backgrounds correctly. Desktop (Compatible) includes special modifications to address this issue.
    • In certain cases, Desktop (Compatible) mode is required, such as when using Game Capture or Window Capture streaming methods.

  5. Open Control Panel > Settings > Desktop > Display Type, and select Window.

  6. Edit the window. In the displayed window area, click the Pencil icon in the top-right corner to adjust the window size or directly drag the window edges.

    Note

    Window size affects EX resource usage. Larger windows consume more resources. Set the window size appropriately.

    Ways to Edit the Window

    • In Control Panel > Settings > Desktop > Display Type, click Edit below.
    • From the tray icon menu, select Edit Window.

  7. Open the edit panel to adjust the model's position and size.

    Ways to Open the Edit Panel

    • In the Control Panel, click in the top-right corner.
    • From the tray icon menu, select Edit Model.

    Window Position and Model Position

    The window position refers to the position of the EX application on the desktop, while the model position refers to the position relative to the window.

Hotkey Settings

  1. Open the Control Panel, select a model from the list, and click Customize ().

  2. In the Expressions and Events lists, assign hotkeys as needed.

    Note

    If the list is empty, ensure that Expressions and Motion Events are correctly configured in the Json file.

  3. Open Control Panel > Settings > General > Hotkeys, and select Always Enable.
