Frequently asked

Does FastPBR Shader work on Minecraft 1.21.4?

Yes. 1.21.4 is the newest Minecraft version FastPBR Shader 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 Shader 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.

How do I install FastPBR Shader?

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 Shader safely?

Start with the author's page on CurseForge, 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.
