Weather Extended
Weather Extended adds weather conditions to NeoForge 1.21.1 that go beyond vanilla rain and thunder, including a radioactive storm, a gray pall and a death pall.
What it does
Weather Extended adds weather conditions that follow the style of the vanilla weather cycle, so they can spawn naturally in a world. The radioactive storm is the exception: it stays off until its configuration option is enabled. Players can expect the new conditions to appear alongside the existing sky states without changing how the game handles time or biomes.
The mod needs WeatherCore to run, and the two are installed together. Weather Extended is published for NeoForge 1.21.1 only, with 0.1.0 as the latest file, released in beta. The code is licensed under the GNU Lesser General Public License v3.0 only, and the source code and issue tracker are public.
The radioactive storm is tied to a separate mod that must be installed for it to work, so a world without that mod has no radioactive storm to find. Installation covers the server and each player's game.
Key features
Gray pall
A weather condition that fills the sky with brown fog and falling ash, and leaves players in the open briefly exposed to a short hunger effect.
Death pall
A stronger form of the gray pall that brings undead mobs with it, while non-undead mobs killed during it leave a different outcome. Wither skeletons can spawn during it.
Radioactive storms
Nuclear explosions from Nucleepers' Nuclear Bombs can leave long-lasting radioactive storms around the blast site.
Weather additions
New conditions such as storms, fog and other sky states are added to the vanilla weather cycle.
