It's not working. This is the first time I've set up uMod and tried to use it and nothing works. I've followed all the instructions and after i update and return to the game nothings changes, no nude mod. Also I'm not sure what you mean by discovering and renaming each file accordingly? What exactly are you doing and how does is fix all this? Super confused about all of this.
What you want to do is rename the file of the character your trying to change to the file name given on the other site.
Then launch U-mod and the game, once the game shows up in u-mod find the file that you renamed and drag in onto u-mods window (should be a large blank spot). The file should then show up in u-mod and you should see the effects in game.
(You might need to go and set it as the default template but not sure if it needed.)
Works for me anyway, though it did take me a couple of tries to get it to work. (still not sure what I was doing wrong)
