Frequently asked

Does [FMCS-L] fps X media X crystal x survival Optimized LITE work on Minecraft 1.21.4?

Yes. 1.21.4 is the newest Minecraft version [FMCS-L] fps X media X crystal x survival Optimized LITE declares support for, and the claim comes from the author's own release metadata rather than from a compatibility list somebody maintains by hand.

Do I need to install [FMCS-L] fps X media X crystal x survival Optimized LITE on the client or the server?

The client only. There is nothing to install on the server, so it works on any server you can already join.

Which loader does [FMCS-L] fps X media X crystal x survival Optimized LITE need?

Fabric. A build for one loader will not load on another, so this is the first thing to check before the Minecraft version.

Which Java version do I need for [FMCS-L] fps X media X crystal x survival Optimized LITE?

Java 21 or newer, because that is what the newest Minecraft release it supports requires. The requirement comes from the game rather than from the modpack itself.

What licence is [FMCS-L] fps X media X crystal x survival Optimized LITE 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 [FMCS-L] fps X media X crystal x survival Optimized LITE?

Install the matching loader first, then put the downloaded file in your mods folder and start the game. The loader, the modpack 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 [FMCS-L] fps X media X crystal x survival Optimized LITE 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.
