Homeostatic Seasons
by wendall911
Homeostatic Seasons changes biomes, weather and plant growth through four seasons split into twelve sub-seasons, with each sub-season lasting three in-game days by default.
What it does
Each sub-season carries its own visuals, weather and temperature changes, so a season shifts how a world looks and feels. Biomes can mix snow and rain at the same time, and temperature is worked out for each block from its surroundings, altitude and the current season. Biomes also change color with the season, and that part is purely visual and does not affect performance. Non-vanilla biomes from major biome mods are supported, and shaders work with it.
Server owners and players can adjust how long seasons last, how strong weather gets and several other settings to fit their preferences. Snow accumulation runs on a chunk-based system that updates only loaded, visible chunks, which keeps large worlds responsive. Plants and other blocks covered by snow are replaced with snow and return to their original state when it melts. Fabric API is required on both Fabric and NeoForge, and the mod is released under the MIT License as open source.

Use cases
Survival worlds
Seasons change weather, temperature and biome colors over time, which gives long survival worlds a steady cycle.
Modded biome packs
Non-vanilla biomes from major biome mods are supported, so seasonal effects can be applied to them as well.
Who it’s for: Players who want seasons that change biomes, weather and temperature, and server owners who want a configurable season system that runs on Fabric or NeoForge.
