Plutonium

I have all my perks changed in bo2 because i could find a tutorial that explained it very clearly for someone that barely knows about PCs and stuff. So im curious to know if there´s a variant for MW3 and WaW.
I know the process is not the same because i tried to change the gold camo and it didn't work somehow. Thanks

I've been trying to make my own mods for a while for myself (Camos Only) but the tutorial is unclear to me and there aren't any videos for help.
I'm no expert in these kinds of things so I'm very insecure about moving a file and breaking the game.

Can someone help me?
