Dirt RT is an ambitious path-traced shader bringing bounced light and physically-based materials to Minecraft. Demanding and experimental, but a fascinating look at real-time ray tracing in the game.

How to install Dirt RT

1. 1Install a shader loader for Minecraft 26.2 — Iris (pairs with Sodium) or OptiFine. Dirt RT is a shaderpack, so it needs a loader to run.
2. 2Download the Dirt RT .zip from the button above — keep it zipped. It is mirrored on MineSpecs, so there is no ad-gate or redirect.
3. 3Drop the .zip into your .minecraft/shaderpacks folder (%appdata%\.minecraft\shaderpacks on Windows, ~/Library/Application Support/minecraft/shaderpacks on macOS).
4. 4Launch the game, open Options → Video Settings → Shaders, and select Dirt RT.

Performance & what to expect

Dirt RT is rated high performance impact. It is demanding — treat it as a showcase pack rather than a survival daily-driver, and expect to tune render distance. It renders path tracing and pbr. The look is realistic. Because it supports PBR, it looks its best with a matching texture set — browse our free resource packs for one with normal and specular maps.
