How do I hide the actor of a unit, for everyone but the owner of the unit?
Try the Filter setting. Check mark the boxes of the players you don't want to be able to see the actor. Which in this case would be: Enemy, Ally.
By default when none is check, the actor is visible to all. Checking a box makes it so that type cannot see the actor.
Use the ghost nuke actors as a guide.
