Live3d IO

Live3D IO is a platform for creating, editing, and streaming 3D VTuber avatars and virtual characters in real time. It provides tools to design custom 3D models, animate them with facial and body tracking, and integrate them into live broadcasts or recorded content. The primary purpose of Live3D IO is to simplify the process of building a virtual persona and using it across streaming platforms without requiring advanced 3D modeling skills.

Key features include a VTuber Maker and Studio that support real-time motion capture using a webcam, iPhone, or other tracking devices, enabling accurate facial expressions and body movements. Users can customize avatars with outfits, accessories, and environments, as well as apply dynamic effects, gestures, and animations during live sessions. The platform offers integration with OBS and major streaming platforms, allowing overlays, scenes, and interactive elements to be managed directly within the Live3D ecosystem. Additional tools support model import (e.g., VRM), scene editing, and performance optimization for smooth streaming.
