About
VSeeFace is a powerful, free avatar puppeteering tool designed specifically for virtual YouTubers (VTubers) and live streamers. It tracks facial expressions — including eye gaze, blinks, eyebrows, and mouth movement — through a standard webcam, with no special hardware required for face tracking. For full-body and hand tracking, it supports Leap Motion devices. The software supports both the VRM0 avatar format and the proprietary VSFAvatar format, which unlocks advanced features such as custom shaders, Dynamic Bones, and Unity constraints. VSeeFace is compatible with the VMC (Virtual Motion Capture) protocol, enabling seamless data exchange with tools like Virtual Motion Capture, Tracking World, and Waidayo. Perfect sync — high-fidelity facial expression mirroring — is available via iFacialMocap, FaceMotion3D, VTube Studio, and MeowFace. For streaming, native transparency capture is supported through OBS Game Capture, Spout2, and a virtual camera output, delivering clean green-screen-free compositing. VSeeFace runs on Windows 8 and above (64-bit) and includes a multilingual UI with Japanese translation support. It is offered completely free for both commercial and non-commercial use, making it a go-to choice for VTubers at any level. The software is actively maintained by developer Emiliana (@emiliana_vt) and receives regular updates.

Use Cases
- VTubers animating a VRM avatar in real time during live streams using only a webcam
- Streamers compositing a transparent avatar overlay into OBS without a physical green screen
- Content creators using iPhone perfect sync via iFacialMocap for high-fidelity facial expressions on their avatar
- Developers and artists previewing and testing custom VSFAvatar models with Unity shaders and Dynamic Bones
- Multi-source motion capture setups combining VMC protocol data from Leap Motion hands and webcam face tracking
Pros
- Completely Free: VSeeFace is free for both commercial and non-commercial use, making professional-grade VTubing accessible to everyone without subscription costs.
- No Special Hardware Required for Face Tracking: Face tracking works with any standard webcam, lowering the barrier to entry for new VTubers significantly.
- Broad Protocol & App Compatibility: VMC protocol support and integrations with popular tools like OBS, VTube Studio, and iFacialMocap make it easy to fit into existing streaming workflows.
Cons
- Windows-Primary Support: VSeeFace is primarily built for Windows 8+ (64-bit); Linux support exists but is unofficial and may require additional configuration.
- No Live2D Model Support: VSeeFace only supports VRM0 and VSFAvatar formats — users with Live2D models must use alternative software like VTube Studio or PrprLive.
- Beta Software: VSeeFace is still in beta, meaning occasional bugs and breaking changes between versions are possible.
Frequently Asked Questions
Is VSeeFace free to use commercially?
Yes, VSeeFace is completely free for both commercial and non-commercial use. You can stream, create monetized content, and use it in professional settings at no cost.
What avatar formats does VSeeFace support?
VSeeFace supports VRM0 avatars and VSFAvatar (a Unity AssetBundle format). Note that VRM 1.0 and Live2D models are not supported.
Do I need an iPhone or special hardware for face tracking?
No. Basic face tracking including eye gaze, blinks, eyebrows, and mouth uses a regular webcam. iPhone-based perfect sync is optional and requires a compatible app like iFacialMocap or VTube Studio.
How do I use VSeeFace with OBS without a green screen?
In OBS, use Game Capture with 'Allow Transparency' enabled, then hide VSeeFace's UI using the ※ button in the bottom right. This gives you a clean transparent background without chroma keying.
What is the VMC protocol and why does it matter?
The VMC (Virtual Motion Capture) protocol is an open standard for exchanging avatar tracking data between applications. VSeeFace can send and receive VMC data, letting you combine inputs from multiple tracking sources or use it alongside tools like Tracking World and Waidayo.
