"Map Lighting leaks from room to room" and other n
 

I cant seem to keep light in my map from leaking through from one room to another where the walls meet. It doesnt leak through doorways just the corners where walls meet at 90 degree angles.

What am I missing? oOo:

Also while Im at it, Im having some trouble getting doors to open in one direction only. Ive set openangles to every angle under the sun yet some doors (Actually shutters) will work but others facing the same direction with the same settings will not. WTF!?!

Thanks in advance.

try putting a thinner wall textured with that inside your walls where this happens, that should block all light
