     the chair may fall off before the mesh
     appears on the scene.
     Keep the chair in the air at first and allow it
     to fall when you let go of your hand.

200. Turn Off Gravity
     ①Use GravityをOff
     ②Is KinematicをOn
     Note︓
     Turn Is Kinematic On to prevent physical interference.
     Prevents the chair from hitting the mesh and flying away
     when the app is launched.
