Not sure what causes this issue.  While using joystick to rotate character in VR, the clouds will rotate speedily the opposite direction in the sky. This causes motion sickness very quickly for experienced VR users.  This rotational bug also effects text on signs causing it to rotate off of the sign board.  As wonderfully immersive minecraft VR was on ps4 VR. The cloud issue makes it unplayable without feeling nauseous fairly quickly.
