Frequently asked

Does Cavernous-X-Patched work on Minecraft 1.21.5?

Yes. 1.21.5 is the newest Minecraft version Cavernous-X-Patched 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 Cavernous-X-Patched support?

Everything the author has declared, from 1.20.2 up to 1.21.5. The full list is in the table above, with the Java runtime each version needs next to it.

Do I need to install Cavernous-X-Patched on the client or the server?

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

What licence is Cavernous-X-Patched under?

LicenseRef-All-Rights-Reserved, 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 Cavernous-X-Patched?

Data packs install per world: put the downloaded file in that world's datapacks folder and run /reload, or add it when creating the world. No loader is involved. On a server, the world folder lives next to the server jar.

Where do I download Cavernous-X-Patched 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.
