Firefly

What is this used for?

Fireflies is a mod for Fallout 4 that recycles the vanilla radiation visual from the Glowing Sea and uses it to spawn fireflies at night.

They may appear in the forests and outback rural areas of Fallout 4's three main world spaces - the Federation, Far Harbor, and NukaWorld, adding even more immersion to your nighttime adventures.

How to install

Use a mod manager like Vortex/MO2.

Alternatively, extract the contents of the rar file into the Fallout 4 Data folder.

Use a mod manager or enable Fireflies.esp (or Fireflies.esl) manually.

How to use it in the game?

This mod comes with a setup holotape that is added to your inventory under the miscellaneous section called "Fireflies". If using a sequencing module such as VIS, the holotape will instead be located under the Settings Holotapes item group.

Under "Weather Settings" you can set the chance of fireflies appearing in different weather conditions.

Under "Time Settings" you can set when the fireflies appear and when they should disappear.

Under Density Settings you can change the frequency of dense firefly swarms versus lighter firefly swarms.

Under the color settings you can change the color of the fireflies.

You can also set whether the fireflies should disappear when shooting starts, or if they should ignore combat entirely.

Of course, if you're on PC and have MCM installed, all of these options can also be set in the mod's own MCM menu, but MCM isn't required, this is just an optional feature for PC players.

compatibility

Compatibility with Far Harbor and NukaWorld is automatic. If you have these extras installed, the mod will automatically detect them and apply the functionality to those world spaces.

This mod runs a very lightweight script that detects if the player is in a cell where fireflies may appear, so it won't conflict with other mods as it won't edit any vanilla cells or world elements.

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.
