Posted August 19, 20223 yr Yo! I'm trying to create a new custom biome, but I don't even know how to start. I'm not trying to change blocks or ore generation from a vanilla biome, I want to change terraforming (and well, also blocks). Here's the biome i want to reply: RockyBiome
August 19, 20223 yr You can make a biome using the datapack mechanism: https://minecraft.fandom.com/wiki/Biome/JSON_format Your mod is automatically a datapack, you place the files in src/main/resources/data Or you can create them in code using the DeferredRegister mechanism. But having a biome won't do you much good unless you have dimension with a ChunkGenerator/BiomeSource that uses it. e.g. your own custom dimension Edited August 19, 20223 yr by warjort Boilerplate: If you don't post your logs/debug.log we can't help you. For curseforge you need to enable the forge debug.log in its minecraft settings. You should also post your crash report if you have one. If there is no error in the log file and you don't have a crash report then post the launcher_log.txt from the minecraft folder. Again for curseforge this will be in your curseforge/minecraft/Install Large files should be posted to a file sharing site like https://gist.github.com You should also read the support forum sticky post.

August 19, 20223 yr Quote What do you mean with that? Exactly what I said, a biome is useless by itself, you need to have a dimension that uses it.

August 19, 20223 yr Not to the vanilla overworld. Things you can do include; * override/replace the vanilla overworld using the datapack mechanism - not recommended for a mod to do by default * use a WorldPreset to create a new "world type" that appears in the "create new world screen" and has a copy of the vanilla overworld with your biome included * use an existing library mod like: https://www.curseforge.com/minecraft/mc-mods/terrablender There are probably other options along similar lines.
