I'm not even joking when I say I know of one modder that messes around with Hrothgar hairstyles. They don't have any professional qualifications, just "I know how to do this and I find doing it cool ". Sometimes the process is easy and straightforward, sometimes they need to adjust the hairstyle a little to make it fit properly and not look like it's just detached from the head or something.
They don't let stuff just hang there, floating stiffly like wire on a bad wig. They don't turn your head into a peanut to pretend like stuff didn't get sloppily stretched to fit. They
care. They are an amateur, but they put care into the stuff that they release, stuff that they aren't paid to do and took time that they didn't have to take to make.
Meanwhile this for Square Enix,
who's been able to give us stuff like this, is such a rocket-science-impossible feat that they just give us stuff in that state and need to do the dumbest thing possible to our head models to make stuff work.
...I'll be cruel here. Really cruel. And I apologize because not only is it cruel-sounding, it's also cruel to say to someone who is Japanese. But no wonder they need to hire new people if this is the best they can do.
