I have been having the same problem in the last 24 hours! Everything is so dark I can't see hardly any details on armor or faces n the parts I can see glow so bright and seem to give off an annoying shine! Also the sky is weird and foggy and the grass glows and it looks like the texture pack I recently got has just up n vanished! Iv tried rebooting reloading taking off n deleting all my mods! And nothing helps I just tried changing the fshadowbias thingy and am waiting for it to reinstall to see if this helps , thank you if it does! n if not I sure hope they fix this up soon I just got my dragonkin woman looking awesome and this happens!! sooo disappointed in last update! ! Bethesda please fix this like yesterday! Concerned Fan!
