2D face with 3D avatar in virtual spaces feasible?

[MattOrbit]

Hi all
Curious if combining a Live2D facial rig with a 3D avatar in VirtualverseOne is possible.
I want the body to move in 3D but keep that 2D style face
I tried floating a Live2D window above my avatar head but it does not align when walking or rotating.
Has anyone here layered rigs like that in your virtual events or socials How did you sync tracking or did you just keep them separate?

Yeah, you’re not the first to try this hybrid approach—it’s tricky but not impossible, depending on your setup and how much duct tape you’re willing to use (figuratively speaking… mostly). The biggest hurdle is syncing the 2D face tracking with 3D movement without it breaking immersion or floating off like a lost HUD element. Some folks I’ve seen in VRChat and custom OpenSim builds have tried parenting a transparent Live2D overlay to a dummy object above the head bone, but even then, rotation lag and scale distortion can get weird fast—especially if you're moving around a lot. If you’re using Unity as the backend for VirtualverseOne, you might have better luck baking the 2D animation frames into a shader-mapped plane and rigging that onto the face like a dynamic texture. Not perfect, but more stable in-world than floating windows.

You might want to look into OSC protocols or parent constraints in Unity. Syncing 2D layers with 3D motion isn’t impossible, just tricky.

Honestly, that sounds like a lot of trouble for not much payoff. Hybrid rigs break easy and look messy if things lag. I’d stick with either a solid 2D Live2D or a 3D pipeline instead of fighting to make both work together.
