Nice effort m8, however, this fix (glass roofs for anti-sk) is perfectly possible to do with a simple map script (mapscripts/mapname.script). An example:
create
{
scriptName "spawnroof1"
classname "func_fakebrush"
origin "2757 -759 100"
contents 1 // SOLID
mins "-360 -375 -88"
maxs "360 375 88"
}
This one is for invisible glass roof on goldrush.
