LuppetX
The company lists its address in Shinagawa, Tokyo, Japan.
What it is
LuppetX is a Windows application for animating 3D VTuber characters with webcam and Leap Motion tracking. It focuses on upper-body expression, including eye and arm movement, and supports hand tracking and lip-sync. The application animates VRM files, including VRM 1.0, and attached accessories can follow character movement. Tracked motion can be sent in real time to external applications through the VMC Protocol, for uses such as streaming, remote meetings, and presentations. The maker describes a setup without prior calibration using a webcam and a Leap Motion worn around the neck. 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. Version 1.1.0 is a free download that works offline and needs no account or license purchase. Personal costs ¥6,600 once; Enterprise costs ¥99,800 once. Support ended October 4, 2026, and the maker says it is dissolving.
