# Animation Patcher

By default, most animations have the **Jaw Close** property set to `0`.\
However, **Sidekick** and many other character models require this value to be set to `1` for the mouth to appear closed.

The **Animation Patcher** tool automatically corrects this by patching animation clips to ensure the jaw remains properly closed.

### Usage

1. **Open the Animation Patcher**\
   From the toolbar, select:\
   **`Tools > HeroBridge Standalone > Animation Patcher`**
2. **Select Animations to Patch**
   * Drag and drop a **single Animation Clip**, or
   * Select an **entire folder** containing animations to process, or
   * Click **Patch ALL** to patch all supported animations in the project
3. **Set the Property Name**\
   In the **Property Name** field, specify the key that should be modified inside the animation.
   * Default: **Jaw Close**
   * Most animations use this property name
4. **Run the Patch**

   * Click **Patch Animations** to patch the selected animations, or
   * Click **Patch ALL** to process every supported animation in the project

   The patch operation **inverts the value**. Running the patch a second time will restore the original value.
