Dependencies

What Structure Layout Optimizerdeclares it needs, from the author’s own release metadata. A required one has to be installed alongside it or it will not load.

Frequently asked

Does Structure Layout Optimizer work on Minecraft 26.3?

Yes. 26.3 is the newest Minecraft version Structure Layout Optimizer 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 Structure Layout Optimizer support?

Everything the author has declared, from 1.16.1 up to 26.3. The full list is in the table above, with the Java runtime each version needs next to it.

Do I need to install Structure Layout Optimizer on the client or the server?

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

Which platform or loader does Structure Layout Optimizer support?

NeoForge, Forge, 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 Structure Layout Optimizer?

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.

What does Structure Layout Optimizer need to run?

It declares Fabric API and Resourceful Config as required, so those have to be installed alongside it or it will not load. Each one is linked in the dependencies section above.

What licence is Structure Layout Optimizer 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 Structure Layout Optimizer?

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 Structure Layout Optimizer 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.
