IWD o.O
1. make a new folder on your desktop; called whatever e.g. "maptemp"
now create new folders in the maptemp:
- "images"
- "maps" /inside a folder called "mp"
- "materials"
- "mp"
- "sound"
- "soundaliases"
these are the basic folders there could be more for own imported models; etc.
images:
If you use custom textures you have to put the *.iwi in "images" ; only
CUSTOM TEXTURES
materials:
and in here the materials files for the custom textures
maps:
inside this folder is an other folder called "mp":
put in this your
mp_mapname.d3dbsp and
mp_mapname.gsc and all other scripts related to your mp_mapname.gsc
mp: ; dont need it but you can add it
in the "mp" folder you can put your
mp_mapname.arena; an arena file contains the info that it is shown in the menu
example:
{
map "mp_lev_facilities"
longname "Lev Facilities Jumpmap"
gametype "dm"
}
map : your mp_mapname
longname: a long name for your map
gametype: the gametypes the map supports make just dm
save that as mp_mapname.arena in the mp folder NOT in the maps->mp
sound:
here your soundfiles in the right folders
soundaliases:
contains your mp_mapname.csv
(make nightmares soundtutorial under codtutorials and you will see)
these were the basic folders
now you make an zip-file:

and make either with winzip or winrar an zip without any compression
now you have a mapnameorwhatever.zip now rename it to mapnameorwhatever.iwd and you' ve got an iwd file
And be sure that you make it like that way and do NOT zip the folder maptemp[/b]

edit:
maybe someone can move that in the cod2->mappingtutorials section
and the skybox tutorial
