Firmament

Your world, in a different light.

Sun on the coast. Clear water below your feet. A village worth coming home to after dark. Firmament gives familiar Minecraft places a warmer atmosphere, using the textures you already have.

Vanilla on the left. Firmament High on the right, in every comparison below.

Warm windows, stars overhead, clouds drifting by. Torches and moonlight give the night its own mood.

The Nether's crimson forests glow. The End feels quieter and more distant. Each dimension keeps its own character.

Start with High. Balanced lowers the cost; Ultra raises the quality. The settings are available in English and Russian.

1. Install Iris and Sodium builds matching your Minecraft version.
2. Drop the Firmament ZIP into shaderpacks. Keep it zipped.
3. Open Video Settings → Shader Packs, select Firmament, and choose High.

This is a client shader; your server doesn't need it. For Minecraft 26.2 and 26.3, use the OpenGL renderer.

Gameplay-tested on Java 1.21.1 / NeoForge 21.1.228 / Iris 1.8.12 / Sodium 0.6.13. The extra Minecraft targets in the download files have automated checks; their game tests, and Fabric game tests, are still pending.

Reflections only see what the camera sees. Waterlogged blocks and overlapping transparent surfaces can show artifacts; underwater reflections are disabled to keep the view clear. OptiFine, ray tracing, PBR, Distant Horizons and Voxy integration are not included.

Real gameplay captures by PozziTiv4ik, High preset, build 0.10-alpha.2. No generated images or colour grading. Later releases optimize that rendering; automated comparisons stay within the project's image-equivalence limits.

By PozziTiv4ik, with editable GLSL included in the ZIP. This shader pack is unrelated to the Hypixel mod named Firmament.
