Shader packs

Shaders replace how the game draws light, water and shadow. They need a shader loader, and the same pack usually behaves differently under Iris than under OptiFine, so both are listed separately.

About Minecraft shader packs

What is a Minecraft shader pack?

A shader pack rewrites how Minecraft draws the world. It needs a shader loader such as Iris or OptiFine, and it costs frame rate in exchange for lighting the game cannot do on its own.

How do I find shader packs that work on my Minecraft version?

Use the Minecraft version filter at the top of the page, and the loader filter beside it. Everything listed under a version declares support for it, so you get the list that will actually load rather than everything that happens to mention the version somewhere in its description.

Where do the downloads come from?

Every shader pack links to its author's own release. MCReference is a reference to what exists and where the official download is; nothing here is mirrored, re-hosted or repackaged.

Which loader do shader packs need?

Shader packs need a loader such as Iris, OptiFine, Canvas and Vanilla. Install the loader first, then the shader pack, and make sure both are built for the same Minecraft version.
