Frequently asked

Does Mount Opacity work on Minecraft 26.3?

Yes. 26.3 is the newest Minecraft version Mount Opacity 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 Mount Opacity support?

Everything the author has declared, from 1.8.9 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 Mount Opacity 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 Mount Opacity support?

NeoForge, 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 Mount Opacity?

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 Mount Opacity need to run?

It declares Fabric API, Mod Menu, YetAnotherConfigLib (YACL) and OneConfig 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 Mount Opacity under?

LGPL-3.0-only, 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 Mount Opacity?

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 Mount Opacity 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.
