Instructions for Creating Face Stickers

Workflow Initialization

Before designing with the plugin, you need to initialize the workspace:

1. Under the Workflow Initialization section, click the Initialize Workspace button.
2. The plugin will automatically create a 2048x2048 canvas named Facebetter_Workspace.
3. The canvas contains 106 standard face reference points.
4. Option: Check "Show Landmark Numbers" to easily identify the numbers of different parts.

Sticker Layer and Attribute Binding

This is the core step of sticker creation, used to define how the sticker follows face movements.

1. Select Layer: Select the sticker layer you designed in the Figma canvas (it must be located within the workspace).
2. Configure Attributes:
   • Blend Mode: Set the fusion effect between the sticker and the face (e.g., Normal, Overlay, Screen, etc.).
   • Position Type:
     • Landmarks: Follow specific face landmarks (most common).
     • Face Rect: Position based on the entire face area.
     • Screen Space: Fixed at a screen position.
   • Trigger Type: Set the conditions for the sticker to appear (Always show, Face detected, Mouth open, etc.).
   • Trigger Delay: Delay time after triggering.
   • Alpha Factor: Adjust the overall transparency of the sticker.
   • FPS: Set the animation frame rate (if the layer contains multiple frames).
