The default sitting animation for a chair in VRChat lines up with your avatar's feet, meaning that the size of your avatar affects how you sit down: Small avatars sink into the seat while tall avatars float above it. We currently have a prefab that fixes this by using a custom chair animation controller to line up the station with the avatar's hip bone, but at the cost of overriding custom hand gestures and emotes. It'd be nice to have this option built into the station so that we can choose to have proper 'sitting' chairs that line up with the hip bone, or 'animation' chairs that line up with the feet (this is what we currently have and works great for dance pad worlds, so retaining this option is important). This way players can sit in chairs correctly without having to sacrifice their self expression through hand gestures and emotes.
