Immersive Weathering is a Minecraft Java mod that makes your world change over time. Blocks age, grow and decay instead of sitting static. It runs on Fabric (1.18.1 to 1.20.1) and Forge (1.18.2 to 1.20.1), and it is required on both client and server. The newest builds, 1.20.1-2.0.5 from 2025-01-23, need Moonlight Lib.
What Immersive Weathering changes
- Moss spreads over cobblestone.
- Bricks become cracked when exposed to extreme heat.
- Iron rusts when it rains.
- Wood blocks char when burnt.
- Icicles form on the edges of roofs.
- Grass actually grows, alongside other similar mechanics.
The damage is not permanent. Cracked bricks can be repaired by using mortar on them. Moss will not grow back if you burn it away with Flint and Steel. The mod is built so you can prevent or repair any damage to your builds. The trade-off is upkeep: a base you leave alone will slowly change.
How to install Immersive Weathering
- 1.Install Fabric or Forge for the Minecraft release you want (see our guides for Fabric or Forge and NeoForge).

Dependencies and limits
On Forge, every build requires Moonlight Lib. On Fabric, builds for 1.18.2 to 1.20.1 require it, while older builds for 1.18.1 to 1.19 need no library. Some 1.19.2 Fabric builds also list optional support for Supplementaries, EMI and LambdaBetterGrass. General steps are in our mod install guide.

Questions about Immersive Weathering.
5 questions
How do I install Immersive Weathering?
Install Fabric or Forge for a matching Minecraft release, then put the Immersive Weathering .jar and the Moonlight Lib .jar for the same loader in .minecraft/mods. Launch with the loader's profile. Older Fabric builds for 1.18.1 to 1.19 need no library.
Does Immersive Weathering work on multiplayer servers?
Yes, but it is required on both sides. Install it on the server and on every player's game, along with Moonlight Lib where the build needs it. A server without the mod will not work with players who have it installed.
Does Immersive Weathering work on 1.21.1 or NeoForge?
No. The newest builds, 1.20.1-2.0.5 from 2025-01-23, are for Fabric and Forge on 1.20.1. There is no NeoForge build and nothing for 1.21.1 or later, so you need Minecraft 1.20.1 or older to use it.
Is there an Immersive Weathering mod for Bedrock?
No. Immersive Weathering is a Java mod, and mods load only on Java Edition. Bedrock cannot run it. To play with it, use Java with Fabric or Forge on Minecraft 1.20.1 or an older supported release.
Can I repair or stop the weathering?
Yes. Cracked bricks can be repaired by using mortar on them. Moss will not grow back if you burn it away with Flint and Steel. The mod is designed so you can prevent or repair damage to the buildings you made.
