Firmament 0.11

Expanded Minecraft compatibility: one ZIP for 29 Java Edition versions.

• Compatibility targets now include 1.18.2; 1.19, 1.19.1, 1.19.2 and 1.19.4; 1.20–1.20.6; 1.21–1.21.11; 26.1, 26.1.1, 26.1.2, 26.2 and 26.3.
• Automatic material selection handles older grass names and newer leaves, flowers, bushes and copper lights. No separate shader ZIP is needed per version.
• Existing lighting, clear underwater surfaces, all three dimensions and Balanced / High / Ultra presets are preserved.

Use the Iris and Sodium builds matching your Minecraft version. Minecraft 26.2 and 26.3 target the OpenGL renderer. Versions outside the list are not included.

The adaptation passed automated source, material and OpenGL checks. Recorded gameplay evidence remains 1.21.1 / NeoForge 21.1.228 / Iris 1.8.12 / Sodium 0.6.13, captured with 0.10-alpha.2 and the same GLSL. Additional Minecraft/Iris combinations still await in-game validation; the new version list is not a claim of 29 game tests.

Keep the ZIP intact, place it in shaderpacks, and select Firmament in Iris. Start with High and adjust the preset for your setup.
