LiveLinkFace ARKit Receiver for Blender

LiveLinkFace ARKit Receiver is a Blender add-on that receives facial tracking data sent from the Live Link Face app on iPhone and automatically applies it to Shape Keys in Blender.

🎨 A simple tool that allows artists to animate their models using their own facial expressions.

🚀 Key Features

📱 Dedicated to iPhone Live Link Face (ARKit mode)

🧠 Supports real-time preview (HUD display of received Shape Key values)
🪞 Ideal for testing Perfect Sync–compatible models
⚙️ Developed and tested with Blender 4.5

❌ Not compatible with the Metahuman protocol (ARKit only)

🧩 Installation

Download the file
Open Blender and drag and drop the downloaded .zip file into Blender.
Check the "LiveLinkFace ARKit Receiver" checkbox and activate it.

📡 How to Use
1. iPhone Settings

Launch the Live Link Face app.
In the settings screen, enter your PC’s local IP address (the one running Blender), e.g. 192.168.0.10.
Use the default port number (11111).

2. Blender Settings

Open the LiveLinkFace panel.
Select the model that includes Shape Keys corresponding to Live Link Face.
Click Start LiveLinkFace.
Shape Key names matching your model will be detected automatically.

When you move your face, the Blender model will reflect your expressions in real time.
🧰 Shape Key Support (ARKit 52 Keys)
This add-on uses Apple ARKit’s standard 52 Shape Key names.
If your model supports Perfect Sync, it will work right away.

The `LiveLinkFace ARKit Receiver for Blender` is a Blender add-on designed to facilitate real-time facial animation by seamlessly integrating data from the iPhone’s Live Link Face app (using ARKit) with Blender’s Shape Key system. Developed by Shun Moriya, the add-on primarily targets artists and developers working with facial rigs, particularly those utilizing Perfect Sync-compatible models.

**Key Features and Functionality:**

* **ARKit Integration:** The core functionality leverages Apple’s ARKit framework on the iPhone to track facial movements.
* **Real-time Preview:** It provides a HUD display on the iPhone showing the received Shape Key values, allowing for immediate feedback during animation setup.
* **Shape Key Mapping:** The add-on automatically detects Shape Key names corresponding to the ARKit’s standard 52 Shape Key names (ARKit 52 Keys), simplifying the integration process. This is crucial for models already configured with Perfect Sync.
* **Simplicity and Ease of Use:** The design aims to be straightforward, intended for artists and developers who wish to quickly establish a live connection between their facial movements and Blender.
* **Connectivity:** The receiver requires the PC to be on the same Wi-Fi network as the iPhone.

**Installation and Usage:**

Installation involves simply dragging the downloaded `.zip` file into Blender. Activating the “LiveLinkFace ARKit Receiver” checkbox initiates the connection. The user then configures the iPhone settings by entering their PC’s local IP address (typically 192.168.0.10) and the default port number (11111). In Blender, the user selects the model containing Shape Keys compatible with ARKit. The ‘Start LiveLinkFace’ command establishes the real-time connection; movements of the face are mirrored in the Blender model.

**Troubleshooting:**

Common issues and their solutions are outlined: if the model doesn’t move, it’s likely an incorrect IP address setting. Value drops or stuttering often result from network delays, suggesting a wired LAN or 5GHz Wi-Fi connection could be beneficial. Shape Key name mismatches are addressed by verifying the Shape Key names within Blender.

**Target Audience and Licensing:**

The add-on’s intended users include artists creating facial rigs, individuals directly testing facial animations in Blender, and developers working with Perfect Sync-compatible models. The software is distributed under the GNU General Public License v3 (GPL-3.0), granting users the freedom to modify and redistribute it under the same terms. The developer, Shun Moriya, encourages users to share feedback through Discussions or Issues, reflecting a commitment to continuous improvement. The developer’s channel, X.com, and YouTube channel, Nonbiri, provide additional channels for communication and support.
