An Inochi2D alternative for Live2D models
Ayatsuri2D and Inochi2D are both free, open-source riggers for 2D puppets. The difference is the format: Inochi2D has its own, streamed with Inochi Session, while Ayatsuri2D works with Live2D's files, so its models load in VTube Studio and every app built for Cubism models.
