Frequently asked

Does One Chunk Biomes work on Minecraft 1.21.11?

Yes. 1.21.11 is the newest Minecraft version One Chunk Biomes declares support for, and the claim comes from the author's own release metadata rather than from a compatibility list somebody maintains by hand.

Which Minecraft versions does One Chunk Biomes support?

Everything the author has declared, from 1.16.5 up to 1.21.11. The full list is in the table above, with the Java runtime each version needs next to it.

Do I need to install One Chunk Biomes on the client or the server?

The server only. Players join with an ordinary Minecraft client and install nothing.

Which platform or loader does One Chunk Biomes support?

Fabric. A build for one platform or loader will not necessarily load on another, so this is the first thing to check before the Minecraft version.

Which Java version do I need for One Chunk Biomes?

Among the supported Minecraft releases above, the highest recorded requirement is Java 21 or newer. Use the requirement for the exact Minecraft version you run; previews and snapshots may differ.

What licence is One Chunk Biomes under?

MIT, as stated by the author on the platform we synced it from. Check the project's own page before redistributing or bundling it.

How do I install One Chunk Biomes?

Install the matching loader first, then put the downloaded file in your mods folder and start the game. The loader, the mod and Minecraft all have to be on the same version, which is the usual reason a mod does not appear in game.

Where do I download One Chunk Biomes safely?

Start with the author's page on Modrinth, which is where the data here is synced from. MCReference does not host or repackage files. When available, recorded download links go to the source for that release; verify the publisher, filename and any available checksum before running it.
