If you walk up to any wall while using a humanoid avatar that has full IK, you're able to get your viewpoint to phase through the wall and separate from your avatar. Look up, turn around, and look straight ahead again; your view will be on the opposite side of the wall. Can continue doing this to move farther away. Avatar teleports to this position if you can see it directly. If there's no wall, the avatar follows the view as expected.
