What I meant by set up in GameMode is just that when you check the editor, it is there (and set from the editor when you change the gamemode through the world settings). My HUD is auntonomous, I just wanted to access it for one particular player.
The HUD is by default stored in the playercontroller. I just used the Unreal functions GetFirstPlayerController()->GetHUD(), it’s client side too, no ? I’m confused, it returns null all the time.
