Photon is a gameplay-first pack: sixthsurge built it around a physically-motivated sky and atmosphere model, then tuned everything so the world stays readable while you are mining, building and fighting. Caves are dark without being unplayable, the sky genuinely changes character through the day, and the whole thing is far lighter than its looks suggest. It has become one of the most recommended packs on the Iris side of the community. Its licence doesn't allow re-hosting, so download it from the author's page.

How to install Photon Shaders

1. 1Install a shader loader for Minecraft 1.16.5 – 26.1.2 — Iris (pairs with Sodium) or OptiFine. Photon Shaders is a shaderpack, so it needs a loader to run.
2. 2Download the Photon Shaders .zip from the button above — keep it zipped. Its licence doesn’t permit re-hosting, so that button takes you to the official modrinth.com page — always the newest build, straight from the author.
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 Photon Shaders.
