Does JME3 attach a unique ID to every element of a scene?

@drothindev The first solution will not be used. The game core is already oriented on using of the numerical IDs. About the second solution – I never used own Controls and don’t understand – what is the difference between using a control and adding an int-field directly to the object which needs the unique ID? By the way, I can not attach an own control to an object in SceneComposer. Maybe it is an issue in SDK – I have used two ways of creating my own control – but they are not appeared in the list of possible controls to be added.
