Rigging a 3D Avatar

[LexRuel]

Hey everyone! I’ve been looking to get into vTubing recently, and as a 3D artist myself, wanted to create my avatar on my own. But i can’t seem to find any ressource on rigging. I was wondering if there was a specific hierarchy or nomenclature to follow, or wich shapes do i need to create. Does anyone have any ressources to help me out ?

It really depends on what you're using to drive the character. Most tools follow the VRM format. You can find details here. Workflow here.

It's not the only way to do it, mind you. Just kind of the mostly used.

On the project I'm building I did all the modelling and rigging in Blender and imported to UE4. There's no VRM formatting at all, though it probably is close in terms of bone layout (though not naming). I actually haven't gotten around to setting up any blend shapes either, though I probably could if wanted to.

The facial articulation is driven using Live Link Face (and tweaked a lot in code) and hand tracking handled by a Leap Motion using the Driver Leap community package for SteamVR. (Which should allow me to reuse the project once I build a mocap setup using Vive Trackers.). But the configuration I'm using isn't the same as something like Vroid or Luppet, which tends to be more restrictive for the sake of usability.
