These basic procedures will show you how the unreal engine works with directories and how to setup your modification so it will use the mod system. This will keep your modification seperate to UT2004 and allow you to work with greater ease and effiency on bigger mods. Personally I always use this as it keeps my base directory free from clutter although if you are working on something smaller like a mutator or gametype you may not need to use this. The best use for this is in total conversion situations where you modification will take up alot of room and have many package's.
The mod system is accessed through the use of
ut2004.exe -mod="your mod"
ucc.exe -mod="your mod"
unrealed.exe -mod="your mod"
I have found that in unreal ed it does not default to your mod's directories, so keep an eye on that when saving anything from maps or packages. If there is a way to fix this please let me know.
Contents
Basic Setup
Engine_Directory_Structure - First we'll start with a rundown of the unreal engines directory structure.
Set_Up_Package_Folders - Then we examine how to setup package's so you can compile.
UT2k4Mod.Ini - We start to get into how to setup your mod to be accessed from the community panel in UT2004.
UT2k4 Default.Ini - This will show you how to setup your mod's default.ini file so you can use it to compile.
Compiling_With_UCC - Lastly to round things off we take a look at how to compile using ucc.exe
Intermediate
Commandlets can be very useful to UScripters, providing automated tasks so you dont have to repetativly do things by hand, The Export Cache commandlet is one example of this. These can also be used to provide language support for various nations.
Custom Characters
You may want to add custom characters or even custom species type to your total conversion, lucky there is a simple way to set it up. Its called the Unreal Player List.
There is special logic built in to the latest patch to make UPL files mod friendly. It works as follows:
When the cache manager searches for UPL files, it traverses the Paths array in reverse (bottom to top) and it checks either directory for .UPL files adding any it finds to it’s cache. When it reaches the game's System, the following occurs:
If you are not running with a mod, it will scan the directory as normal.
If you are running a mod, no .upl files have been found already, it will scan the directory as normal.
If you are running a mod, and the game has already found even a single .upl file, it will skip the default System directory.
In a nutshell, this means that if you have a mod that uses both your own custom .upl files and you want to allow them to use the default characters, you will need to include a copy of the original .upl files with your mod.
Advanced Importing
When working with large amounts of assets it might be alittle overwhelming to do this by hand through unrealed. Now alot of the time unrealed will let you import multiple files at once but sometimes it is much easier done on the command line. It free's up valuable memory that can be used to get the process done quicker without the overhead of the full editor open.

Discussion
OlympusMons:Ok so I created this page to pull all the mod system stuff together into a format I can use to make a tutorial. Alot of it is in basic prodecure type pages but I think it'll work very well like that. Im going to work a bit more on this page dont worry, if there is another page on this topic and I missed it please let me know and I'll give this a deleteme. Im hoping to add it to the UnrealScript_Lessons page when Im finsihed.
