I am a vtuber and my main avatar/model is a custom 3D model created in blender by LumaVT. I commissioned it. I also sometimes use a Live2D model, check my credits for more info here.
☆What tracking do you use?
I use the pc program VSeeFace paired up with an iPhone 11 and the app iFacialmocap for ARKit facial tracking. The modelling and rigging for my model was done by LumaVT. I also have an Ultra Leap Motion controller for hand tracking!
