Frequently asked

Does Concurrent Chunk Management Engine work on Minecraft 26.3?

Yes. 26.3 is the newest Minecraft version Concurrent Chunk Management Engine 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 Concurrent Chunk Management Engine support?

Everything the author has declared, from 1.17.1 up to 26.3. The full list is in the table above, with the Java runtime each version needs next to it.

Which platform or loader does Concurrent Chunk Management Engine support?

Fabric, NeoForge. 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 Concurrent Chunk Management Engine?

Among the supported Minecraft releases above, the highest recorded requirement is Java 25 or newer. Use the requirement for the exact Minecraft version you run; previews and snapshots may differ.

How do I install Concurrent Chunk Management Engine?

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 Concurrent Chunk Management Engine safely?

Start with the author's page on CurseForge, 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.
