I'm not sure why creating a revealer didn't work for you, but that's what I've always done when testing my maps. I think you only have to create one revealer per team as well as long as teammates have shared vision, but I haven't tested that.
Visibility - Create a visibility revealer for player 1 within (Entire map)
That's exactly what I use, it's working in my map right now.
I haven't experimented with blocking vision in an area no matter what, so I'm sorry to be no help there.
Also I think there used to be another option for the mask in the Map Options, maybe that was removed recently. That said, all that did was remove the fog of war. It didn't reveal units/structures etc. on the map at all times.
