This tutorial will explain how to use & install Umod files. These topics will be explained:
I assume you have a working knowlege of the operating system you are using, and that you have already downloaded a .umod file to experiment on.
This one is very simple. At least, when everyting is working OK. In Windows, just double-click on the .umod file, and it shoud fire up an installer wizard. When asked for a directory, simply type in your UT dir, ie. C:\Games\UnrealTournament. If you're running Linux, download the Platform independent umod installer, and follow the instructions provided.
This will be in a Q&A style. Of course, this list is not complete. If you've had any error message that is not in here, please leave a message at my forum, and I'll add it to this list.
This ususally indicates a corrupted Manifest.ini. There are some lines and sections that must exist in Manifest.ini. You can read them here. Don't simply replace your Manifest.ini file with these lines, but make sure they are there.
A corrupted Manifest.ini can be caused by creating an UMod package without the use of UModWizard.
Unfortunately, this menu is very fragile. If any mod is doing something wrong, all could go to hell. Well, not really. Check out which mutator is shown last in the menu. It is either this one, or the next mutator (alphabetially speaking) that is giving the problems.
You can remove a mutator from the menu, by opening its .Int file, and putting a ';' in front of the line that has 'MetaClass=UMenu.UMenuModMenuItem' in it. Remove the mutator that is giving problems (or might give problems) from the menu, and see if that fixes things. If not, remove some more mutators from the menu. Experiment a little, and in no time you should be able to find out which one is giving trouble. Keep the broken mutator from the menu. You can configure it by manually editing its .ini file.
Another possibility is that the mutator doesn't use the mod menu at all. You can tell, because it hasn't got a line containing 'MetaClass=UMenu.UMenuModMenuItem' in its .int file.
This depends on the contents of the Umod file. If it is a map or a skin, you sould be able to select it from the appropriate menu and use it right away. For mutators, it is actually the same story, but people seem to have some trouble with it. So here is how to activate the mutator.
