🎯 Tips & Tricks
If you're using a mod manager like Vortex or MO2, just download and install — the meshes will overwrite automatically.
Make sure this mod loads after any terrain or landscape overhauls to ensure the underside meshes take priority.
If you're on the next-gen update, check the mod's comments for user reports on compatibility before installing.

⚠️ Common Mistakes
- Installing multiple mods that modify the same files without checking compatibility
👍 Pros

- Covers all major map areas, so you get consistent fixes across the base game and DLCs
- Lightweight and performance-friendly — just mesh files, no scripts or heavy assets
👎 Cons
- Last updated in 2022 — may not be fully compatible with the latest Fallout 4 updates or next-gen patch
- No detailed install instructions or compatibility notes provided by the author
