Immersive Weathering
by Ordana
Immersive Weathering adds natural aging to blocks: moss spreads over stone, bricks crack in heat, iron rusts in rain and icicles form on roof edges.
What it does
Stone and brick slowly change over time. Cobblestone can gain moss, bricks can crack when exposed to extreme heat, and wood blocks char when burnt. Iron rusts when it rains, icicles form along the edges of roofs, and grass spreads in ways that follow the surroundings. The changes are meant to age a world without weighing down the game or altering buildings more than needed.
Damage from these mechanics can be undone. A cracked brick can be repaired with mortar, and moss can be removed with Flint and Steel, which prevents it from growing back in that spot. The author describes this repair and prevention as the main way players keep their builds intact. Immersive Weathering requires Moonlight Lib, which must be installed alongside it on Fabric or Forge.
The server and every player need the mod installed. Files are published for Fabric and Forge across five release versions, 1.18.1 – 1.20.1, and the latest files are 1.20.1-2.0.5 for 1.20.1, released 2025-01-23. The code is released under the GNU Lesser General Public License v3.0 only, so it is open source, and public links exist for the source code, issue tracker and wiki.
