What LuppetX is

LuppetX is a Windows application for animating 3D VTuber characters using webcam and Leap Motion tracking. It focuses on upper-body expression, including eye and arm movement, and also lists hand tracking and lip-sync. The software animates VRM files, including VRM 1.0, and can make attached accessories such as ribbons, cat ears, necklaces, or microphones follow character movement. Tracked motion is sent to external applications in real time through the VMC Protocol. The maker describes uses such as OBS chat or game streaming, avatar meetings, and presentations. Requirements include 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 and needs no server connection, account registration, 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; the maker says it will no longer answer inquiries or provide fixes or updates, and that the company is dissolving.
