Only Snow

A premium, custom world generation Fabric mod for Minecraft 26.1.2 that restricts the Overworld entirely to snowy and icy biome variants, while maintaining complete vanilla compatibility for other dimensions.

❄️ Features

Snow-Only Overworld: All Overworld biomes dynamically map to their snowy counterparts at sampling time:
- Plains, forests, jungles, taigas, deserts → Snowy Plains / Snowy Taiga
- Oceans & Rivers → Frozen Ocean / Deep Frozen Ocean / Frozen River
- Beaches → Snowy Beach
- Mountains & Slopes → Frozen Peaks / Jagged Peaks / Snowy Slopes / Grove
Two Custom World Presets:
1. Only Snow Biomes: Standard biome sizes and vanilla structure/animal spawn frequencies.
2. Only Large Snow Biomes (Less Structures): Harsh mode featuring horizontally stretched biomes (larger, wider mountain ranges and spread-out ice spikes) with a 95% reduction in surface structures, trees, vegetation, and passive friendly animals.
Vanilla Conservation: Underwater generation (seagrass, monuments), ruined portals, underground structures, strongholds, mineshafts, trial chambers, and other dimensions (Nether/End) are kept 100% untouched.
Modern Config UI: A beautiful, fully custom configuration screen cycling button controls with zero external dependencies, accessible via Mod Menu.
Compatibility First: Fully compatible with temperature/survival mods (like Cold Sweat) and performance mods. Includes built-in engine redirects to prevent crashes with Level-of-Detail caching mods (like Voxy) and input managers (like Controlify).

🖥️ Server-Side Configuration

If you are hosting a dedicated server, you can configure the mod directly using server files:

1. Selecting the World Preset

Before launching the server to generate the world, set the level-type property in server.properties to one of the following:

Only Snow Biomes (Normal Biomes): level-type=only_snow:only_snow
Only Large Snow Biomes (Less Structures): level-type=only_snow:only_large_snow

2. Custom Spawning & Structure Rates

You can configure the generation and spawning rates on the server by editing the config/only_snow.json file:

{
  "structureReduction": 95,
  "animalReduction": 95,
  "treeReduction": 95
}

🤝 Known Compatible Mods

Only Snow is designed with compatibility in mind. It has been tested and verified to work flawlessly with the following popular mods:

Mod Menu: Full in-game configuration integration via our custom settings screen.
Cold Sweat: Perfect integration with temperature mechanics. Because Only Snow maps to vanilla snowy biomes, freezing temperatures operate natively.
Voxy: Level-of-detail rendering works without any saving or file-locking crashes due to our custom save-redirect mixins.
Controlify: Fully compatible with controller/input setups.
Sodium: Renders the vast snowy and icy landscapes at high framerates.
Lithium & C2ME: Dynamic multithreaded worldgen and chunk tick optimizations operate without conflict.
