Hello, I'm not sure what the status of your project is, but is it possible to view the source code and make contributions? I'm a cs student and I'm interested in learning more about your project, maybe even helping in a substantial way.
The ultimate goal is to get vTuber Kit to an open source point. So yes, eventually! I just have 1 major asset left to replace and we should be able to open source from there, but it could be a number of months still.
