Montarc — Horizon shader pack

Montarc exists because, when Muurrcc started it, Horizon's registry had no shader packs at all. The look is close to Complementary Reimagined — bright, saturated, warm sunsets — but the code is the author's own, written from scratch in WGSL. It's for players who want a vivid, cheerful world rather than a moody cinematic one, and who like tinkering: there are 29 options.

Features

• Soft shadows from the sun and moon; water and stained glass tint the light passing through.
• Matching sky and fog: blue days, orange sunsets, deep blue nights. Far terrain fades into the sky with no hard horizon line.
• Coloured light: warm torches, blue soul fire, red redstone, cyan sea lanterns, purple amethyst.
• Water: waves, depth colour, reflections, sun glitter and shoreline foam.
• Wind: grass, flowers, crops and leaves sway, more strongly in rain.
• Nether and End: a hot, hazy Nether with heat shimmer; a cold, purple End.

Compatibility and install

Shader pack, version 1.1.1, for Minecraft 26.3. It needs a Horizon nightly from 2026-11-04 or newer. Install it from the Shader packs tab on the launcher's Mods page (it goes into shaderpacks), then select it in Options > Horizon Settings > Shader Packs. See our shader install guide.

Known problems

The author lists them openly. Horizon's shader API is version 0.1, experimental, and may change. Entities, block entities and particles aren't shaded yet. The Nether and End skies stay vanilla because the sky stage only draws in the Overworld. Some GPUs show stripes until you tune Shadow bias. Licensed MIT.
