3D Layout contains one of the most important property: ParentName. This property is used to declare what object this label belongs to. By setting a parent to the label, we can make it follow the action of the parent including the movement. The following steps demostrate how to set a parent to the label:
Select the label in the Storyboarder(Setup node) and make sure the Properties tab is active.
Make sure the Scene is active as well.
Move the cursor to the object that you want to set as the parent in the Scene tab, click on it with the mouse key keeping down and drag it to the ParentName slot.
