Okay I got a quick one. I had an ENB mod installed. I didn't like how bright it was. There was a glitch on some textures where it would be super white. So I uninstalled it. Simple enough. I even did a complete Skyrim reinstall. I need to know what the default texturing of the hay roofs looks like at Ravenrock. I'm not sure if there is some linger glitch or the texturing is bad or what. So here is a screenshot of what Skyrim downloaded as the default texture.

The problem in question is how it looks like there is some sort of plastic dirt covering the roof of the house. I can't find better words for it. Is it supposed to look like that? Or is my game still messed up? Running at max.

procedural generated ash effect, similar to the snow effect. Yeah it does look like that, sadly.

Okay thanks I just wanted to be sure. God that is one ugly roof. Haha.
