Frequently asked questions

How do I get started with Biome Replacer?
Open your world's configuration folder and find biome-replacer.properties. Add a line in the format old_biome > new_biome, save the file, and restart the server for the change to take effect.
What is the exact format for a replacement rule?
Each rule goes on its own line as old_biome > new_biome, using the biome's registry ID. The greater-than symbol separates the biome you want to remove from the one you want in its place.
Do I need to restart the server after editing the config?
Yes, the mod reads the properties file at server startup, so changes only apply after a restart. Reloading the world without restarting will not pick up new rules.
Will Biome Replacer change biomes in chunks that already exist?
No, it only affects newly generated terrain, so existing chunks keep their original biomes. To see replacements, you need to explore new areas or generate fresh chunks.
