Out of Bounds (Trigger)

Game Modding | Call of Duty: Black Ops 3 | Radiant

eDeK:

I put the trigger "Out_of_bounds" in my map, when im inside the trigger i can see the effect "distortion" in my screen, but i cant see the message "Return to the combat zone" like in multiplayer.
I need to put a special "#using" or something?.
Thanks.
