Oh, well thanks for setting me straight there. Even though I wasn't trying to be authoritative or knowledgable.
LIES! Nah, I wasn't trying to come off like that(tired and all that so no offence meant

) There are a few packs, but they're few and far between. Most stuff is custom, and you need to add it via the CS and so on. But for people looking for clean head/body textures and meshes I'd say start looking around japanese mod sites, since they seem to kick them out in quick order and they are compatible with the US/Euro versions minus the text issues for descriptions which are in japanese/etc.

There's also been some really promising stuff coming out of china as well. I'd link to a few of the sites but Beth gets cranky when you link to sites that have non-locked(aka requires login like nexus) advlt content.
eh I'll risk it again this time
