Brioche Puppet: Free & Open-Source VTuber Software

Dive into the world of virtual expression with Brioche Puppet, a powerful and free, open-source VTuber software. Create stunning and interactive avatars using a variety of industry-standard formats and advanced rendering techniques. Whether you're a seasoned streamer or just starting out, Brioche Puppet provides the tools you need to bring your virtual persona to life.

Supported Model Formats & Animation

Brioche Puppet supports popular 3D model formats including MMD PMX format and VRM (and glTF) format, offering seamless integration with a wide range of pre-existing avatars. Animate your models with ease using supported motion asset formats like MMD VMD or leverage real-time motion capture via video detectors powered by MediaPipe for accurate hand, face, and pose tracking. You can also connect to external motion sources using the VMC Protocol through the built-in motion receiver.

Advanced Physics & Rendering

Experience realistic physics simulations with the integrated Bullet Physics engine, adding dynamic movement and engaging interactions to your VTuber avatar. Brioche Puppet features cutting-edge rasterization rendering and physically based rendering (PBR) techniques, including Lambert and Trowbridge Reitz shading. Achieve a stylized look with customizable toon shading options, featuring celluloid face shadow maps, three base colors, and rim lighting effects. The software uses directional lighting, area lighting with linearly transformed cosines, and environment lighting with spherical harmonics for realistic lighting and reflections.

Global Illumination (Voxel Cone Tracing)

For high-end systems, Brioche Puppet offers Global Illumination (Voxel Cone Tracing) for advanced lighting effects. Note that this feature is performance-intensive and may not be suitable for all setups, especially when using toon shading.

Future Development: Expanding the Possibilities

Brioche Puppet is constantly evolving, with ongoing development focused on advanced features such as skin rendering (subsurface scattering), directional lighting shadow maps (irregular Z-Buffer), ray tracing (ReSTIR), and even neural rendering (Gaussian Splatting). Stay tuned for future updates and exciting new possibilities for your virtual avatar!
