When connecting to servers to play online, some of them will download files that you don't have but need to play. I use UT CacheCleaner to put these files into their correct directory, so that I will always have them. The map files are downloaded as complete maps meaning that I can play them without doing anything special. While checking the textures directory I noticed a lot of files that are for skins, but are not automatically converted to skins. What programs do you guys use to easily convert these textures files to playable skins?
