Frequently asked

Does RFTools Dimensions work on Minecraft 1.21.1?

Yes. 1.21.1 is the newest Minecraft version RFTools Dimensions 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 RFTools Dimensions support?

Everything the author has declared, from 1.8.9 up to 1.21.1. The full list is in the table above, with the Java runtime each version needs next to it.

Which loader does RFTools Dimensions need?

Forge, NeoForge. 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 RFTools Dimensions?

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 mod itself.

How do I install RFTools Dimensions?

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 RFTools Dimensions safely?

From the author's own page on CurseForge, 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.
