so i was considering quest pro for the eye and face tracking for vrchat, but i dunno.. seems kinda pointless.
avatars already have animated eyes which don't really match real eye positions but basically it's close enough since nobody really notices that in vrc.. same with the mouth.. you can already have the mouth animated based on the analysis of the sound when you talk, so having mounth track would be useful for the rare occasion if you want to open your mouth while quite or some shit
so it doesn't really seem worth the money to only have this small improvement in facial animations, definitely not like fbt which is a huge easily visible difference
