Frequently asked

Does DirtTW's Basement Optimize Pack work on Minecraft 1.21.8?

Yes. 1.21.8 is the newest Minecraft version DirtTW's Basement Optimize Pack 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 DirtTW's Basement Optimize Pack support?

Everything the author has declared, from 1.19.4 up to 1.21.8. The full list is in the table above, with the Java runtime each version needs next to it.

Do I need to install DirtTW's Basement Optimize Pack on the client or the server?

The client only. There is nothing to install on the server side. That is the author's declared design, not a guarantee for every server: one running anti-cheat or missing a counterpart mod can still object.

Which platform or loader does DirtTW's Basement Optimize Pack 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 DirtTW's Basement Optimize Pack?

On the newest Minecraft version it supports, Java 21 or newer. The requirement comes from the Minecraft version you run rather than from the modpack itself, so on an older supported Minecraft the answer is that version's Java, not this one.

What licence is DirtTW's Basement Optimize Pack 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 DirtTW's Basement Optimize Pack?

Use a launcher that imports packs, such as Prism Launcher, the Modrinth App or the CurseForge app, and open the pack file with it. The launcher installs the right loader and mods for you; installing a pack's mods by hand is the error-prone way.

Where do I download DirtTW's Basement Optimize Pack 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. The download link goes to the source recorded for that release; verify the publisher, filename and checksum before running it.
