Block lighting?

[JavaGuy]

I have a huge gate in my map that swings open (it's a func_static) partway through the level. Outside the gate is outdoors, so when it's open all the light comes in. When it's closed it should be fairly dim inside. When I compile, however, the room inside the gate is brightly lit.

 

Because the other indoor rooms don't have this problem, I suspect what is happening is that because the gate is a func_static it is essentially not even there for purposes of calculating lighting. Is there any way around this? Is there some non-solid brush I could use to block the light coming in without creating a HOM?

I thought that only worked inside a func_door.

They can work with other - script moved - entities, you just have to use the SET_ADJUST_AREA_PORTALS with them.
