That's it, I give up, I cannot solve this shader problem. I have deleted many caches and backup files, redownloaded and cut and pasted shader files time and time again, and gone throught the whole process of reinstalling. Nothing will work.
Edit: Hey, should I have a file under mods called "xpack"?
Edit Edit: Seems that I should. But really, this bug is fucking frustrating me, I would like to be able to play FH again.
