your fallback only has to be <10k tris for the quest version, just upload a cope cube that tells them to get a real headset.
the PC version of your fallback can be 70k polys and like 8 materials. don't forget to put a little notice on the avatar or on the head that says it's a fallback, or else you'll get really confused people. if you have a "proper" fallback avatar, people may not recognize that it's a fallback.
