The one which I got working seems to no longer be on my machine. I have looked at the "alicia" model which is in openseeface-gd it will crash VTuberWebcam and Blender seems to not be able to import it. I'm not sure if that project is working with Godot 3.4 official release. I ran into an error with it when I tried.
I'll look at these other exporters.
The other tools could be useful to.
Thank you.
