Frequently asked

Does Oct-Path work on Minecraft 1.21.11?

Yes. 1.21.11 is the newest Minecraft version Oct-Path 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 Oct-Path support?

Everything the author has declared, from 1.16.5 up to 1.21.11. The full list is in the table above, with the Java runtime each version needs next to it.

Do I need to install Oct-Path 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 Oct-Path need?

OptiFine. 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 Oct-Path?

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 shader pack itself.

What licence is Oct-Path under?

LicenseRef-Custom, 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 Oct-Path?

Install the matching loader first, then put the downloaded file in your mods folder and start the game. The loader, the shader pack 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 Oct-Path 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.
