LuppetX is a tracking system for 3D Virtual YouTubers
that only requires a web camera and LeapMotion
Specialized in upper body expression, various ingenuities are incorporated so that the character moves lively with just two devices.
Just hang the LeapMotion on your neck and point the camera at yourself.
It is developed with the aim of being used by a non-computer-savvy streamer alone.
You can move the character by simply converting the 3D model to VRM.
It also supports the latest VRM standards (VRM1.0).
We have prepared documentation to solve various questions such as preparing 3D models and devices, and how to use LuppetX.
“Luppet”, the predecessor of LuppetX, has been supporting VTubers’ broadcasts worldwide since its release in February 2019.
And thanks to the feedback from our users, various updates have been made.
It is designed to allow anyone to become a VTuber by minimizing the necessary equipment and preparation, even if they are not very familiar with computers.
Please watch the video.
While keeping the concepts and features of the conventional Luppet intact, we have redesigned everything from scratch.
In X, based on Luppet, we have added features such as ‘Accessory function’, ‘Motion transmission to external applications’, ‘Transparent background’, and ‘Behavior improvements during tracking loss’.
In addition to these, we have improved memory usage and GPU load compared to before.
From Game Streaming to Remote Meetings
We expect it to be used for chat streaming and game streaming using OBS.
On the other hand, it can also be used for things like remote meetings and presentations using avatars.
By purchasing a license, you can use it for commercial purposes regardless of whether you are an individual or a corporation.
As of May 2023, Luppet is used by more than 100 companies worldwide and over 13,000 individual VTubers.
