I'm not particularly into VTubing (not a fan of social streaming or the japanese style), but i find the tech and creativity amazing. I'm very into mocap and started building an experimental facial capture system, which overlaps a lot with the VTubing concept, but using different protocols (most VTubing models/solutions uses VMC) and more varied custom cartoon models.

If you are into the tech behind mocap this community is a fun place to explore.
