Frequently asked

Does FastPBR work on Minecraft 1.21.4?

Yes. 1.21.4 is the newest Minecraft version FastPBR 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 FastPBR support?

Everything the author has declared, from 1.18.2 up to 1.21.4. The full list is in the table above, with the Java runtime each version needs next to it.

Do I need to install FastPBR 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.

What licence is FastPBR 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 FastPBR?

You need a shader loader first: Iris (with Sodium) or OptiFine. Put the downloaded file in your shaderpacks folder and select it in the video settings shader screen. The shader loader, not the pack, decides which Minecraft versions work.

Where do I download FastPBR 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.

Works on the same versions

Ordered by how much of the recent Minecraft version coverage overlaps, not by popularity.

Details from Modrinth, where the author last updated it on 28 Feb 2025. We do not host files or republish descriptions. Available download links point to the author’s own release.
