It took a lot of trial and error and comparing files from every one to get to where I am at now (and I am sure I will be adding more!). I spent many, many hours working on my current loadout of appearance mods for males and females.
So you might think you are using a mod, when actually another of your mods may have copied its own files over it. What makes it worse is that many of them overwrite others either completely or in parts.
There is a dizzying array of mods out that to add new bodies, face textures, and so on. This has come up a few times in other threads, so I thought it might be good to have a topic devoted to our characters and their makeover mods.
