Introduction

Have you ever experienced this? You are walking through the Commonwealth in a storm. Rain poured down, thunder rolled, and lightning flashed across the sky...

Then suddenly, the rain just... disappeared.

Look to the left. rain.

Look to the right. rain.

You look straight ahead. It didn't rain.

Turn around a little? here we go again.

congratulations. You've just encountered Fallout 4's rain bug.

This mod fixes this issue.

Now, when turning, changing direction, or emerging from the water,

Rainwater remains visible, while bridges, roofs, and other shelters still properly block rainwater. It also includes protection for the air-wet environment map, preventing other problems that could cause rainfall and wetness effects to disappear unexpectedly. Each fix can be individually enabled or disabled in the accompanying INI file.

Install

Use your favorite mod manager to install the correct version for your game.

A built-in INI file allows you to enable or disable repair.

Install & use Install: follow the bundled instructions

  1. Unzip the archive from playbuff and read the bundled readme / instructions first.
  2. There is no universal mod manager for this game: some mods replace game files directly, some go into a game-specific Mods folder, and some need a game-specific community loader or tool first — follow the bundled readme.
  3. Place the files exactly as the readme says; mods with listed dependencies need those installed too.
  4. Launch the game to confirm it loaded; some games require enabling mods in settings or an in-game mod menu.

Install locations vary a lot between games and mods — the bundled readme is the most reliable guide.
