Look at: ShotGlass

ShotGlass
*Linkage: BUG( Stays blank hitting any part of the body or even clicking on the scene list of Avatar.1 )

Look at: Set Free

ShotGlass
Linkage: Avatar1-RightHand

Now it works.

Look at: ShotGlass

Now it works.

*Linkage or Attach have the same bug.

So if the character looks at after it is parented or linked then it works but not the other way around.
