ВЕРСИИ (9)

The Nether, rebuilt. Every Nether biome now has its own air and light, the lava sea glows and lights the smoke above it, and light sources glow where they really do. The weather fixes of 0.3.3, which was never published, come with it. ### New - **Five biomes, five moods:** warm red smoke over the Nether wastes, deep crimson in crimson forests, violet air around warped forests, a cold blue-green haze in soul sand valleys and grey ash in basalt deltas. The look changes smoothly at biome borders, and biomes from other mods get smoke in their own colour. - **Drifting smoke:** banks of smoke rise and drift through the Nether, thickest just above the lava sea, where it glows orange. The end of your render distance melts into the smoke. - **Heat shimmer** over the lava sea. - **Light from below:** overhangs and ceilings above the lava sea glow warm. - **New Nether screen** in the shader settings: Drifting smoke and Heat shimmer. ### Changed - **Lava with heat:** a deep red crust, orange melt and yellow-white veins that glow, with slow currents drifting across lava seas. - **Light sources:** torches and lanterns glow only in the flame, glowstone and shroomlights glow all over in their own colour, Nether portals and crying obsidian glow purple, and soul fire flames stay blue. ### Fixed - **White snowfall:** snowflakes fall bright and white instead of as faint grey specks. - **Dry where it does not rain:** snow no longer turns dark and glossy in a snowfall, and deserts stay dry while it rains somewhere else. - **Water under clouds:** the sparkle of the sun on water dims under cloud shadows, and caustics fade out in a storm. - **Volumetric light off:** the sky overhead stays as clear as with the option on; turning it off now only removes the light shafts. - **Held light:** a torch in your hand also lights nearby smoke and particles. ### Compatibility - The same 29 Minecraft Java versions as 0.3.2: 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.

Smoother skies, wetter rain. Two small image fixes, at the same speed as 0.3.1. ### Fixed - **No more banding:** sunsets, the night sky and fog fade smoothly instead of in visible steps. - **Rain looks wet:** wet ground turns darker and glossy instead of milky white. The sun and moon no longer glare off the ground through storm clouds; after the rain, a low sun still glints on wet paths. ### Compatibility - The same 29 Minecraft Java versions as 0.3.1: 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.

Faster shadows, steadier sunsets. A maintenance release for 0.3.0: the same look and settings, more frames per second and four lighting fixes. ### Performance - **More FPS:** the shadow map is drawn only from chunks within the shadow distance instead of everything up to your render distance. In our test scenes (1920 × 1080, High, render distance 16) that gave about 10 % more frames per second, and up to 30 % at dusk with the light behind you. ### Fixed - **Calm dusk and dawn:** light, shadows, light shafts and the sparkle on water no longer jump to the other side of the sky the moment the sun sets. Sunlight fades out, then moonlight fades in. - **Sunset clouds** keep their warm afterglow after the sun has gone down. - **Backlit plants:** grass, flowers and leaves glow softly against the sun instead of turning dark. - **Clear caves:** rain haze and morning mist stay outside. ### Compatibility - The same 29 Minecraft Java versions as 0.3.0: 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.

Richer colour, calmer light. Firmament no longer looks as if the brightness were turned all the way up: colours stay saturated, daylight has contrast, and nights, caves, the Nether and the End keep their mood. ### New - **Morning mist:** low fog in valleys and over water at sunrise (optional). - **New settings:** Eye adaptation, Contrast, Vibrance, White balance, Vignette, Sharpening, Morning mist and Milky Way, in English and Russian. ### Changed - **New tone curve:** a hue-preserving filmic curve keeps mid-grey where it belongs. Sunlit sand and blossoms keep their colour instead of fading to white; only real highlights such as the sun roll off to white. - **Juicier colour, not neon:** vibrance lifts sky, sand, blossoms and grass, while snow stays white and already vivid colours stay natural. - **Eye adaptation:** centre-weighted metering, and dark scenes are no longer lifted to daylight brightness. Bloom only comes from truly bright light. - **Sky:** a deep blue sky with a blue horizon, warm twilight bands, a sun halo, moon phases, twinkling stars and an optional Milky Way. - **Clouds:** white sunlit tops over grey bases. - **Light:** torches and lanterns fall off naturally from golden to amber, and lava stays orange. - **Nether and End:** relit. The Nether is dark and deep instead of a glowing red wall; the End island has shape instead of a flat white surface. - **Rain** falls as grey streaks. ### Compatibility - The same 29 Minecraft Java versions as 0.2.2: 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. The new gallery was rendered in Minecraft 1.21.1 / NeoForge 21.1.228 / Iris 1.8.12 / Sodium 0.6.13 on the High preset. ### Known issues - After reloading chunks with F3+A, shadows of blocks outside your view appear once you look at them: Iris only builds chunks the camera sees. ### Notes - Use the Iris and Sodium builds matching your Minecraft version; 26.2 and 26.3 target the OpenGL renderer.

Faster clouds in rain and tidier shader code, with exactly the same picture. ### Changed - **Under the hood:** repeated shader code now uses shared helpers, the reflection-snapshot pass decodes each pixel once, and unused declarations are gone. ### Performance - **Clouds in rain:** about 1.05× faster. Cloud samples that are already fully dense skip noise that cannot change them; higher Cloud Coverage settings benefit too. - **Nothing slower:** every other pass costs the same as in 0.2.1. Four further optimization ideas were measured and left out because they were not faster. - Timings are isolated GPU pass measurements against 0.2.1 on an RTX 4060 Laptop GPU at 2560 × 1440 with the High preset, not frame rates. The sky, fog and night-sky speed-ups of 0.2.1 are kept. ### Compatibility - The same 29 Minecraft Java versions as 0.2.1: 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. - Use the Iris and Sodium builds matching your Minecraft version; 26.2 and 26.3 target the OpenGL renderer. Recorded gameplay evidence remains 1.21.1 / NeoForge 21.1.228 / Iris 1.8.12 / Sodium 0.6.13 with 0.1.0-alpha.2. ### Known issues - After reloading chunks with F3+A, shadows of blocks outside your view appear once you look at them: Iris only builds chunks the camera sees. ### Notes - **Same image:** every automated comparison image is bit-identical to 0.2.1; rendering, presets and options are unchanged. - Keep the ZIP intact, place it in `shaderpacks`, select Firmament in Iris, start with High and adjust the preset for your setup.

A cleaner shader core and a faster sky, with the same look. ### Changed - **Under the hood:** shared shader code is reorganized, with named materials and one implementation of each lighting helper. Every other pass costs the same as in 0.2.0. ### Performance - **Sky:** the atmosphere pass computes the sun and moon once per frame instead of once per pixel and is about 1.3× faster by day and night. - **Fog and light shafts:** 1.06–1.17× faster above and below water. - **Night sky:** stars and clouds over open sky about 1.06× faster; ambient occlusion reconstruction about 1.03×. - The figures are isolated GPU pass timings measured against 0.2.0 on an RTX 4060 Laptop GPU at 2560 × 1440 with the High preset, not frame rates. In-game FPS depends on the scene, render distance and hardware. ### Compatibility - The same 29 Minecraft Java versions as 0.2.0: 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. - Use the Iris and Sodium builds matching your Minecraft version; 26.2 and 26.3 target the OpenGL renderer. Recorded gameplay evidence remains 1.21.1 / NeoForge 21.1.228 / Iris 1.8.12 / Sodium 0.6.13 with 0.1.0-alpha.2. ### Known issues - After reloading chunks with F3+A, shadows of blocks outside your view appear once you look at them: Iris only builds chunks the camera sees. ### Notes - Rendering, presets and options are unchanged from 0.2.0; automated OpenGL comparisons match it within the project's equivalence limits. - Keep the ZIP intact, place it in `shaderpacks`, select Firmament in Iris, start with High and adjust the preset for your setup.

Performance release: more frames, the same look. ### Performance - **Nether and End:** the unused sun shadow map is no longer rendered at all. - **Overworld shadows:** a depth-only shadow pass; water and clear glass no longer reach the shadow rasterizer. - **Cloud shadows:** read from a small map computed once per frame instead of several noise octaves per lit pixel. Sunlit surface lighting costs less than half as much as in 0.1.1. - **Fog and light shafts:** cheaper shadow lookups along each ray (about 1.2×). - **Sky:** clouds and stars are rendered after the terrain. Stars are drawn only where the sky is visible; in caves and sealed rooms, clouds hidden by terrain cost much less (about 2.4× for a cave view with a strip of sky). - **Ambient occlusion:** open, unoccluded areas skip the reconstruction filter. - The figures are isolated GPU pass timings measured against 0.1.1 on an RTX 4060 Laptop GPU at 2560 × 1440 with the High preset, not frame rates. In-game FPS depends on the scene, render distance and hardware. ### Compatibility - The same 29 Minecraft Java versions as 0.1.1: 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. - Use the Iris and Sodium builds matching your Minecraft version; 26.2 and 26.3 target the OpenGL renderer. Recorded gameplay evidence remains 1.21.1 / NeoForge 21.1.228 / Iris 1.8.12 / Sodium 0.6.13 with 0.1.0-alpha.2. ### Known issues - After reloading chunks with F3+A, shadows of blocks outside your view appear once you look at them: Iris only builds chunks the camera sees. ### Notes - Rendering, presets and options are unchanged from 0.1.1; automated OpenGL comparisons match it within the project's equivalence limits. - Keep the ZIP intact, place it in `shaderpacks`, select Firmament in Iris, start with High and adjust the preset for your setup.

Expanded Minecraft compatibility: one ZIP for 29 Java Edition versions. ### Compatibility - 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. - Use the Iris and Sodium builds matching your Minecraft version; 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 0.1.0-alpha.2 and the same GLSL. Additional Minecraft and Iris combinations still await in-game validation; the new version list is not a claim of 29 game tests. ### Notes - Existing lighting, clear underwater surfaces, all three dimensions and the Balanced, High and Ultra presets are preserved. - Keep the ZIP intact, place it in `shaderpacks`, select Firmament in Iris, start with High and adjust the preset for your setup.

The first release: natural lighting, clear water and a new atmosphere for all three dimensions. ### Features - Soft shadows, volumetric clouds, atmospheric fog and shafts of light. - Reflective water above the surface, with a clear view from underwater. - Smoother water reflections without the earlier nighttime star streaks. - Warm block lighting, moving foliage, wet surfaces, bloom and automatic exposure. - Balanced, High and Ultra presets, with English and Russian settings. ### Compatibility - Tested in Minecraft Java 1.21.1 with NeoForge 21.1.228, Iris 1.8.12 and Sodium 0.6.13; other game versions and renderer combinations remain untested. ### Notes - The author captured the gallery with High in the Overworld, Nether and End. - Keep the ZIP intact, place it in `shaderpacks`, select Firmament in Iris, start with High and adjust the preset for your setup.
