Hey, something I've noticed is that VSeeFace will track eyebrow movement but not in VtuberPlus. Is this a limitation of this software?
For any animation or tracking to work outside of VSeeFace you must make sure that the blendshapes are available on the avatar. Eyebrows are "Brows up" and "Brows down". If they are missing, they can not be transfered using the VMC protocol. More info on the special blendshapes can be found here: https://www.vseeface.icu/#special-blendshapes
