Brioche Puppet — Free and Open-Source VTuber Software

Brioche Puppet is a comprehensive toolkit for live virtual performances. It combines flexible model and animation support with advanced rendering, physics, and input technologies to help creators bring avatars to life with depth and personality. Built to be accessible yet capable, it emphasizes openness and community-driven development while delivering professional-grade features.

Asset and animation support

• Import and use character models from MMD PMX, VRM, and glTF formats to fit a variety of art styles and rigs.
• Animate with motion data in MMD VMD format, enabling traditional choreography workflows and fan-made motions.

Input, detection, and motion networking

• Leverage MediaPipe-based video detection for real-time hand, face, and pose landmark tracking to drive avatar expressions and gestures.
• Use the VMC protocol for motion Receiver to connect and synchronize performances across networks, enabling live collaboration and streaming setups.

Physics and rendering

• Ragdoll physics powered by Bullet Physics adds believable body dynamics and interactions for on-camera movement and scene contacts.
• Rasterization rendering with physically based shading provides realistic material responses. Toon shading offers a stylized look featuring a dedicated face shadow map system, three base colors, and rim lighting for bold, expressive visuals.

Lighting, global illumination, and environments

• Directional lighting, area lighting via Linearly Transformed Cosines, and environment lighting using spherical harmonics create rich, cinematic scenes.
• Global illumination through Voxel Cone Tracing enhances indirect lighting for scenes that demand depth and realism—recommended primarily for high-end hardware and certain toon shading workflows.

In-progress enhancements

• Skin rendering with subsurface scattering is under development to improve realism of skin tones and translucency.
• Ongoing work on directional lighting shadows using Irregular Z-Buffer, as well as ray tracing and neural rendering experiments, aim to push fidelity and performance in future updates.

Brioche Puppet targets streamers and creators who want a versatile, open platform for expressive VTuber performances. It bridges traditional model workflows with modern detection, physics, and rendering techniques to empower both simple and advanced setups without locking users into a single pipeline.
