GeoGradient - Climate Generator

By alkeari.devOwner , Alkeari

Real-world geography for Minecraft. The further you travel north or south, the colder or hotter the world becomes, with poles, equators, and seven climate bands that actually make sense.

Description

Biomes stop being a patchwork. GeoGradient lays climate across the world in latitude bands, so you ride from equatorial jungle through temperate forest into tundra and finally polar ice, the way a real globe is arranged.

Minecraft 1.21.1 on Fabric or NeoForge, and 1.20.1 on Fabric or Forge. Needs Architectury API.

⭐ What It Does

  • Climate follows latitude - hot at the equator, cold at the poles, with the full cycle repeating every two globe-widths so the world stays infinite.
  • You set how big the globe is - anywhere from 1,000 to 1,000,000 blocks from a pole to the nearest equator.
  • The bands are not straight lines - noise warps every border, so a coastline of climate wanders instead of ruling a stripe across the map.
  • Transitions are blended, not butted together - each boundary gets a cosine-blended zone sized as a fraction of the narrower neighbor.
  • Start where you want on the globe - an optional spawn latitude drops a new world at the equator, at a pole, or anywhere between.
  • Terrain shape is untouched - it hooks vanilla's biome source and, when present, TerraBlender. Mountains and caves stay exactly as your other mods made them.

📋 Requirements

  • Minecraft 1.21.1 on Fabric or NeoForge, and 1.20.1 on Fabric or Forge.
  • Architectury API 13.0.8 or later on every loader.
  • Fabric API 0.110.0 or later, Fabric Loader 0.16.9 or later, and Cloth Config API 15.0.140 or later, on Fabric.
  • NeoForge 21.1 or later, on NeoForge.

📥 Installation

  1. Install your loader and Architectury API, plus Fabric API and Cloth Config if you are on Fabric.
  2. Install with the CurseForge app, or download the jar for your version and loader into your mods folder.
  3. Create a world and travel north or south. The climate changes as you go.

⚙️ Configuration

Settings are read when the Overworld loads. On Fabric the file is config/geogradient.json; on NeoForge it is config/geogradient-common.toml.

Setting Default What it does
globe_size 10,000 Blocks from a pole to the nearest equator, 1,000 to 1,000,000. The full cycle repeats every two of these.
border_amplitude 200 Maximum Z-axis warp applied to biome borders by noise, in blocks, 0 to 10,000.
border_frequency 0.002 Frequency of that border noise, 0.0001 to 0.1. Lower is broader waves, higher is tighter ripples.
spawn_latitude 0.0 Where a new world spawns, -1.0 at the equator to 1.0 at the north pole. 0.0 leaves spawn alone.
blend_fraction 0.15 Width of the blended transition at each band boundary, 0.0 to 0.5, as a fraction of the narrower band.

NeoForge enforces those ranges. On Fabric a value outside its range is clamped when the world loads.

🖥️ Compatibility

  • Existing worlds. Chunks generated before you added the mod keep their biomes; only new columns follow the climate bands. Expect a visible seam at the edge of explored terrain.
  • Client or server. It changes world generation, so it goes on the server and on every client.
  • Spawn is set once. The override runs on first world load and leaves a marker in the world folder, so changing spawn_latitude later does not move an existing world's spawn.
  • TerraBlender is used when it is installed, and skipped cleanly when it is not.
  • Terrain shape, caves and structures are untouched, so mods that change those work alongside it.

🐛 Support

  • Include your Minecraft version, your loader and its version, the mod version, and your other mods.
