Frequently asked

Does Aio's Extra Structures! work on Minecraft 1.21.1?

Yes. 1.21.1 is the newest Minecraft version Aio's Extra Structures! 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 Aio's Extra Structures! support?

Everything the author has declared, from 1.21 up to 1.21.1. The full list is in the table above, with the Java runtime each version needs next to it.

Do I need to install Aio's Extra Structures! on the client or the server?

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

What licence is Aio's Extra Structures! under?

CC-BY-4.0, 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 Aio's Extra Structures!?

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 Aio's Extra Structures! safely?

From the author's own page on Modrinth, which is where the data here is synced from. MCReference never mirrors, re-hosts or repackages a file: every download button points at the original source, so you get exactly what the author published.
