Making air ducts?

How did they make those 'air ducts' such as on Flap and Rotcannon which allow the players to rise up and down?

The internal volume of the "down" ducts are filled by a trigger_gravity brush that reduces the gravity for players that are inside it. The "up" ducts have a trigger_multiple->target_push at their base that points to a target_location at the top of the duct.

So the down ducts would be a nodraw brush with that trigger? I might try the gravity brush thanks

You could use the trigger shader...
