try ''texture cull'' in the command box in ued for texture stuff, if its sound or music or other stuff try to find where you used it, and delete the actor there and save it, it should be gone then though
but if you mean that you got for instance Jailbreak installed and that your ued loads up JB textures and stuff when starting then thats justbecause of the mod, it wont involve with the map, you can turn it of if yoiu want
UnrealTournament.ini
search for [Editor.EditorEngine]
then under it you have a list (this is my list, not a default one )
EditPackages=Core
EditPackages=Engine
EditPackages=Editor
EditPackages=UWindow
EditPackages=Fire
EditPackages=IpDrv
EditPackages=UWeb
EditPackages=UBrowser
EditPackages=UnrealShare
EditPackages=UnrealI
EditPackages=UMenu
EditPackages=IpServer
EditPackages=Botpack
EditPackages=UTServerAdmin
EditPackages=UTMenu
EditPackages=UTBrowser
EditPackages=ExtendedBuilders
EditPackages=TarquinBrushBuilders
EditPackages=TarquinExtrudeBuilder
EditPackages=Jailbreak
EditPackages=JBArena
delete the line of the pack you dont want in ued anymore, should work then, oh and dont delete things like core or browser

cause then it could happen it doesnt work anymore
