I know there is a mod on sorcerers that changes the way combat looks, but is there also something out there that can alter what the characters build looks like in game?

For instance, human males look a bit to bulky, like they are all bodybuilders or something, and half elves look like humans instead of elves (I thought that half elves looked like elves to humans, and like humans to elves). Besides, some of the faces are... well, horrible (HUGE moustache and a generals hat?).

Well anyway, if someone knows of a mod that changes thes things, I'd be gratefull. I like humans, but I don't like looking like a bodybuilder when I have only 10 strength and am playing a rogue or monk, or anything that does not wear heavy/medium armour).

I don't think anyone has ever gone changing the already existing basic models apart from dozens of jiggly and non-jiggly genitalia mods... But there certainly are many new head models and retextured bodies available. So there's a lot of material in this area, but I don't recall off-hand any changes to the male models of the kind that you're after.

The official expansions also add more customizing options for clothes and new heads.

The Community Expansion Pack gives you loads of new heads, cloaks on armour, heraldic shields and the like, but does nothing for the bodies, Im afraid. Also, as with most custom content with NWN, it has to be preloaded into whatever module you're playing, so for instance you cant use the new heads in the OC, SOU or HOTU.

Thats about it, Im afraid.

CEP is a *collection* of different custom content made - CEP features hardly any original content.

And custom content may be added through override folder too, though that works only singleplayer.

Searching the vault (http://nwvault.ign.com) is probably your best bet.
