📋 About This Mod
Bethesda forgot to invert the Y axis of the sunlight direction, which means the offset is the opposite of the actual sun.
I fixed it in Fallout New Vegas 2 years ago, stop asking me about it. It's in Stewie's Tweaks.

✨ Key Features
📊 Pros & Cons
✅ Pros
- Community-approved fix with 789 endorsements—clearly solves a real issue for many players.
- Tiny download size means no performance hit or bloat.
- Actively maintained (last updated April 2024) so it's likely compatible with current setups.
⚠️ Cons
- Only addresses one specific visual bug—if you haven't noticed the sunlight issue, this mod does nothing for you.
- Requires FOSE, so you'll need to install that dependency first if you haven't already.
For Fallout 3 players who've noticed the sun looks off and want a quick, community-approved fix. If you're a purist who wants the game's lighting to be as accurate as possible, this is for you. Skip if you're not bothered by the sunlight or if you don't want to bother with FOSE.
💡 Beginner Tips
- Install FOSE first—it's required for this mod to work. Make sure you launch the game through fose_loader.exe, not the default launcher.
- Since this is a simple fix, you can just drop the files into your Data folder, but using a mod manager like Vortex or Mod Organizer 2 makes uninstalling easier.
- If you're using other lighting or weather mods, test this fix after those to ensure no conflicts—though it's a small change, it's worth checking.
