Whenever, I end up going into a snowier region, everything except the HUD turns pure black. I can use the console's forced weather to set the weather to something else, but of course the weather will quickly change back to whatever weather is causing this problem. Things I have tried that don't seem to fix anything: -Disabling all mods. -Removing all loose files in Data (I think, but it's possible I missed some). -Updating/rolling back drivers. -Deleting Skyrim.ini and SkyrimPrefs.ini I was also having a huge problem with sunbeams being all black with the Climates of Tamriel mod, but disabling that seemed to fix it. Just thought I'd mention it in case this is a more global lighting problem.
