Lumen — Horizon shader pack

Lumen by Lutziano888 goes for a cozy, warm mood inspired by the look of Photon, but it's original code written in Horizon's own shader format, with no Minecraft assets. The registry tags it "medium", so it's aimed at mid-range hardware rather than top-end cards. Picture a riverside farm at sunset with fireflies over the grass, and you've got the target.

Features

• Soft sun and moon shadows.
• A warm sky with a round sun and golden sunsets.
• Volumetric clouds that cast drifting shadows.
• Light shafts through trees, sun rays, bloom and distance haze.
• Clear water with waves, refraction, reflections and sun glint.
• Turquoise water with caustics when you dive.
• Waving leaves, grass, flowers and seagrass.
• Coloured block light and glowing fireflies.
• Wet ground after rain.

Compatibility and install

Shader pack, version 2.1.0, for Minecraft 26.3. It needs a Horizon build from 2026-11-03 or newer. Install it from the Shader packs tab on the launcher's Mods page, which drops it in your shaderpacks folder, then pick it under Options > Horizon Settings > Shader Packs. Our shader install guide shows each step.

Limitations

2.1.0 is the pack's first registry release, published on 6 November 2026. The author gives no performance numbers, so check your FPS before settling in. Horizon's shader API is still version 0.1 and experimental. MIT licensed.
