How to attach Actor to HMD camera

I tried to attach a simple cube to the HMD camera position to be visibile everywhere I look but I cant get it work, as soon as I move the HMD, the cube stays at its initial position. Any ideas how to achieve this? I tried to attach the component in the VRPawn blueprint, but that way I can’t rea variables inside the LevelBlueprint.

What do you mean you cannot read variables in the Level Blueprint? The variables of the cube actor?

I can help you, but your post is not exactly clear about what the problem is.
