Most of my map is coming together smoothly, except for 2 things-

Glass- this is what i get
http://img230.imageshack.us/my.php?image=glassuh9.jpg

any advice on how to fix this?. I've tried 1unit wide brush textured all faces, textured one face, no draw on all but one face, patches etc etc but I still see that gap through the edges

Rain- i've got rain working fine, sounds good nice and heavy, but it comes through ceilings. I've tried adjusting the z coord from 0-to height of buildings and upwards no joy though, damn leaks!

	level._effect[ "rain_heavy_mist" ] = loadfx( "weather/rain_mp_farm" );
	maps\mp\_fx::loopfx("rain_heavy_mist",(0, 0, 0), 1);
