How do you create an interior cell with no oxygen?

[CyberBeedrill2077]

So I'm trying to make an underground facility with breathable and non breathable sections separated by airlocks. The problem is I don't know how to make non breathable areas where the player has to wear a helmet.

 

I know the Airlock_Volume object can be used to designate an area as breathable on an airless surface world space, but I'm not aware of any opposite version that designates an area as non breathable.

 

I added the ENV_Loc_NotSealedEnvironment keyword to the location attached to the interior but it didn't have any affect.

 

Is their a guide that goes over this specific issue? What am I missing that I need to do?

There is an Actor Value associated with that.  You need an Activator to set the Actor Value.

I only vaguely know how activators work or what an actor value is but thanks for at least pointing me in the right direction.
