COMPILING: If you want to compile the .map file provided, keep in mind there will 
be a few errors when you try to compile, they are as follows:

!!! Very Important: You have to compile this map with -lomem 
for the light process or it will not compile. 
It will report an error: safe malloc failed in allocation of xxxxxxxxx bytes 
and quit compiling in the beginning of the light compile process.

In order to add -lomem to the compile process in GTK radiant 
go File --> Project Settings then where it says "Menu commands" 
find the compile process you want to use, say change, then 
in the new window that pops up where it says "command" scroll near 
to the end of the command and find -light -fast

after "-fast" add in -lomem. Also change the "menu text" 
appropriately in order to remind you which compile process has -lomem enabled.


Some other unimportant errors I should mention:

The map editor might report: Entity Leaked 
This is not a problem as it isn't a real leak, 
it appears to be a strange phenomena of the map editor I was using, 
if you want to try and fix it anyway, I'd recommend redoing the outermost skybox, 
and it will probably be fixed.

There will be about a dozen errors about detail brushes defaulting to structural, 
ignore this, it has to do with the areaportals in the doors, if you want to get rid of it, 
find the offending portals and make sure they're set to structural in the editor not detail.

Reminder:

Oh and in case you hadn't thought to do this, you'll need to extract all of the folders 
in the corheights2.0.pk3 into your own base directory, but be careful since 
this might overwrite rooftop.shader and sound.txt. I believe that is all it could 
overwrite but it never hurts to backup, I accept no responsibility for problems 
and errors you may encounter.
