OS Weather

By
LevelsFR

A dynamic, localized weather and atmospheric simulation system for Minecraft.

Fog can roll in and completely change the mood of an area with soft visibility and atmospheric depth.

Cold regions can develop into intense snowstorms with dense snowfall and very limited visibility.

Dry climates can turn hostile with powerful sandstorms and reduced visibility.

OS Weather also enhances calmer moments with more natural cloud coverage and atmospheric transitions.

Description

🌦️ OS Weather

A dynamic and localized weather experience for Minecraft.

About

OS Weather transforms Minecraft's Overworld with a dynamic, localized atmospheric simulation.

Instead of a single global weather state, different regions experience their own conditions influenced by biomes, temperature, humidity, pressure and wind.

From clear skies and rainfall to snowstorms and extreme weather, the atmosphere evolves naturally as you explore.

One world. Different climates. A living atmosphere.
