When the in-game sliders for adjusting Look-At-Me Offset are used VRChat sends either the new value for the Horizontal Offset with the address /usercamera/LookAtMeYOffset or the new value for the Vertical Offset with the address /usercamera/LookAtMeXOffset over OSC (whichever has changed), but when VRChat receives a float over OSC on address /usercamera/LookAtMeYOffset it changes the Vertical offset and then loops back the float sent on both /usercamera/LookAtMeYOffset and /usercamera/LookAtMeXOffset. The same also occurs when VRChat receives a float over OSC on address /usercamera/LookAtMeXOffset, it changes the Horizontal offset and then loops back the float sent on both addresses.
