Lawrence’s Ambient Fireflies Data Pack adds floating particle effects to swamp biomes across your world. The pack runs lightly in the background without causing lag during your travels. When you walk through muddy waters at night, tiny lights float in the air around trees and ponds. It brings extra life to murky wetlands while keeping vanilla gameplay completely intact.

Lawrence's Ambient Fireflies Data Pack

Features:

  • Spawns ambient firefly particles across Swamp and Mangrove Swamp biomes.
  • Uses a lightweight setup that keeps world performance smooth and fast.
  • Works alongside most standard data packs in singleplayer worlds and custom servers.
  • Conflicts only with other packs or mods that directly alter swamp biome files.
