IK misbehaving in VR
Foot IK targets are placed higher in VR than they are in desktop mode with "Allow my avatar to stand" set to "Always", and with it set to "When I'm standing" the head is too far down and the avatar hunches over.
I wonder if that avatar has a root bone or something that is further down than the rest of the avatar. In my experience, issues with avatars being too high either only happen to specific avatars, or are caused by faulty animations (both happen is desktop mode as well).
We have a user height setting but that isn't used by IK, as far as I can tell it just rescales your avatar to something like (height / 170) cm
This happens on humanoid avatars too and appears as tippy toes
This might be a problem with user height calculation, on basically any avatar your legs will be stretched taught by default and tilting your head can pull your feet off the floor or bend your knees.
