How can I mod maps and areas???

I need a full tuto that says exatly how to mod maps and areas please.

Don't forget that you can only mod textures of an area. You can mod areas as you mod armors or monsters.

First of all, you'll need this: http://lightphenix.free.fr/modding_files/Models_Maps.rar This is an archive which contains all the maps

Then you'll need this: http://lightphenix.free.fr/modding_files/Ref_MAPs.rar
You must extract this file in the directory _Remplir/ref/

And then, you'll need this: http://lightphenix.free.fr/modding_files/MOD_Map.bat
This is a window's script. You must place it beside the MOD_creation.bat file. Just launch it and follow the instructions. If you have questions about it, don't hesitate, we'll answer it
