I suppose some mods or textures (if you swapped them) affect the situation.
I advise you to remove all the mods and see if that fixes the situation.
If it does, install mods back one by one and this way you’ll find the guilty one.
Then just either not use it or look for updated version of the broken mode/texture
From what I understand, this is to do with mods conflicting with how the materials got changed in the Raytracing update. I had the exact same symptom with a rather lovely mod that gives 47 a holster and such. If you have any suit replacements, uninstall them one by one until you find the naughty mod, then reinstall until all naughty mods are purged.
Hi, I know I am incredibly late to this post, but for anyone else experiencing this and the aforementioned solutions above don’t work:
Make sure you haven’t enabled sparse-grid super-sampling of any kind. For whatever reason, it makes everything look wet or shiny, and is incredibly easy to replicate for those curious.
