Being inside Skyrim is a lot different than looking at it from the outside. When you're playing Skyrim VR on the Oculus or HTC Vive, you don't take things like weather and huge cliffs for granted.
That's why it's important for every little grain of sand, every drop of water, and every flak of snow to look downright gorgeous. That's where this mod comes in to play.
Better weather effects revamps the whole color scheme of the game and provides an increased level of immersion while trekking from Whiterun to the College Of Winterhold. Couple this with the Skyrim 2017 textures mod, and you'll be in a brand-new Elder Scrolls worlds you never knew existed.
