HowItWorks

BiomeRemap is based on a simple idea: Imagine that we discovered a perpetually cold world, where ice and snow covered everything, even deserts and swamps. It would be a new Ice Age, without the Woolly Mammoths.

BiomeRemap makes that possible, by remapping biomes as chunks are generated in configured worlds. We can configure a cold world that will be covered in ice and snow. Or we can configure a temperate world that will have universal rain, or a hot world where it never rains. Conveniently, the original terrain, flora, mobs, and structures are retained. (Of course, only mobs consistent with the new biomes will be spawned after the biomes have been remapped.) The configurations are world-specific.

Remapping is generally triggered by player movement through the world, but can also be forced with commands or with third-party plugins that generate chunks. Performance for player-generated chunks is acceptable, but for the best player experience, larger regions should be pre-generated using tools such as Chunky (preferred) or Chunkmaster or WorldBorder.

BiomeRemap is provided for your enjoyment and entertainment. We cannot guarantee that the results will meet your needs or desires.

⚠️ Caveats and warnings

The most important caveats:

• Unmapped chunks. Chunks generated before BiomeRemap is enabled (or installed) will need to be remapped with commands. See World Repair for more details.
• Biome remapping cannot be reversed. Always backup the server before using this plugin, and test the functionality before you use it on a production server.
• Region remapping is a cpu-intensive activity. During region remapping, TPS will drop well below levels that support interactive play. It should be performed only on a quiescent server, with no players on-line. For the best player experience, worlds should be pre-generated using tools such as Chunky (preferred) or Chunkmaster or WorldBorder.
