Welcome to the OWL VTuber Studio open repository! VTuber Studio features the vast capabilities of the Off World Live Live-Streaming Toolkit for VTubers, game streamers, and content creators.
VTS provides streaming and capture functionalities in-game and in-editor, providing an open-source project template for users to quickly customize and package their own VTuber Studio.
VTS provides useful blueprints and example assets for you to easily package your UE project into a standalone VTuber Streaming Studio.
Using persistent levels, you can seamlessly import your own environments and avatars to recreate and customize your own VTuber application with preconfigured capabilities for streaming.
This project uses Git LFS (Large File Storage), please clone VTuber Studio with 'git lfs pull' to receive all assets.
