What LuppetX is
LuppetX is Windows software that animates 3D VTuber characters using a webcam and Leap Motion. It focuses on upper-body expression, including eye and arm movement, and supports hand tracking and lip-sync. It works with VRM files, including VRM 1.0, and can make attached accessories such as ribbons, cat ears, necklaces, or microphones move with the character. Tracked motion can be sent in real time to external applications through the VMC Protocol, for uses such as OBS streaming, avatar meetings, and presentations. The listed 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 setup without prior calibration. Version 1.1.0 works offline without an account or license purchase. It 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.
