LuppetX vs VNyan

LuppetX is a Windows application that animates 3D VTuber characters using webcam and Leap Motion tracking. It focuses on upper-body expression, including eye and arm movement, and supports hand tracking and lip-sync. The software animates VRM files, including VRM 1.0, and attached accessories such as ribbons, cat ears, necklaces, or microphones can follow the character. Tracked motion is sent in real time to other applications through the VMC Protocol, for uses such as OBS streaming, avatar meetings, and presentations. The stated requirements are Windows 10 64-bit, a GTX 970 or better, an Intel Core i5-4460 equivalent or better, 8 GB RAM, an Ultraleap device, and a webcam. The maker describes a setup without prior calibration: wear Leap Motion around the neck and point a webcam at yourself. Version 1.1.0 works offline and needs no account or license purchase. That version is a free download; Personal costs 6600.00 JPY once, and Enterprise costs 99800.00 JPY once. Support ended October 4, 2026, and the maker says it is dissolving.

VNyan is a free Windows application for creating 3D VTuber animations, stages, tracking setups, and stream interactions. Its Node Graph interface lets users build actions ranging from chat responses to more complex events. It supports VRM, VRM 1.0, and VSFAvatar models, with 2D and 3D avatar workflows and VRM import. Tracking includes SteamVR full body, webcam ARKit face tracking, iPhone trackers, LeapMotion hands, and incoming VMC protocol. Integrations include Twitch, YouTube, Kick, Chaturbate, Fansly, Joystick.tv, and Pulsoid. VNyan supports Spout2 and NDI capture and accepts WebSocket commands from tools such as Stream Deck and Streamer.bot. Effects include audio lip sync, frequency and volume detection, AudioLink shaders, liquid and pendulum physics, and post processing. VNyanNet enables collaboration, while the SDK supports custom plugins, items, props, and worlds. Optional NSFW integrations, including Lovense support, can be hidden. The listed download is VNyan 1.7.2e, with the SDK also available.
