So I'm not a big fan of those "handdrawn" portraits for conversations, and I downloaded some other portraits instead. That's all good and fine, but now my character's hairstyle and hair-color doesn't fit the portrait, and I can't find anywhere to change it. There's no "import/export" feature like in the Baldur's Gate series. And I know it's a small thing, but it's been bugging me for a couple of hours now, and I know it'll keep bugging me until I find a way to solve it - or start over from the beginning (which I don't really feel like at this moment...). Does anyone know how to (if at all possible) change the hair color and style of a character?
