I'm really interested in building live "VTuber" rigs with MetaHumans that can play instruments live. Unfortunately I'm only a drummer lol so my options are pretty limited i.e. no piano, singing, guitar, etc.
I recently discovered "Tabla Touch" which are basically electronic tablas with MIDI output! I spent a day rigging this basic MetaHuman rig to have the hands play one "stroke" each. The face is stock MetaHuman logic using the LiveLinkFace iOS app.
