PMWU-AO
PMWU-AO Atmospheric Overhaul changes how atmosphere, storms and weather spawn and behave on NeoForge 1.21.1.
What it does
The overhaul reworks the atmosphere of the world, changing how storms form, where they appear and how they move through the sky. It is built for NeoForge and targets Minecraft 1.21.1 only, with no other game versions in the catalog. Only the client needs it, while a server may add it or skip it, since either side can run without it.
Key features
Overhauled atmosphere
Atmospheric conditions across the sky are reworked, so the look of the world changes during play.
Storm spawning
Storms spawn under different rules, which alters where and when bad weather shows up in a world.
Weather behavior
Once a storm is present, its behavior over time is changed to suit the reworked weather system.
Compatibility
