🌌 Lumina Event Horizon v1.3.8 — End & Nether Evolution

The End grows more mysterious, the Nether becomes more atmospheric, and Lumina Event Horizon receives major compatibility and performance improvements. ✨

🕳️ Event Horizon Improvements

• Restored the wide, luminous accretion-disk glow.
• Preserved the animated disk, gravitational lensing and cosmic movement.
• Restored the White Hole energy rays.
• Added smooth nine-sample terrain occlusion for the rays.
• Added occlusion support for Distant Horizons terrain.
• Prevented rays from appearing through terrain or outside the viewport.
• Kept the White Hole and its rays independently configurable.

⚡ End Performance

• Added early angular rejection for the Black Hole and White Hole.
• Expensive procedural-noise samples are now skipped outside their visible areas.
• White Hole disk noise is only calculated where it contributes to the final image.
• Terrain occlusion remains calculated in the vertex pass to protect performance.
• Visual quality, animation, accretion glow and energy rays remain preserved.

🔥 New Nether Atmosphere

Available on Windows and Linux:

• Added biome-aware fog colors and densities.
• Added smooth 15-second transitions between Nether biomes.
• Added the new Nether Biome Fog Strength control from 0% to 150%.
• Rebalanced lava toward a warmer, natural orange glow.
• Reduced excessive exposure around large lava lakes.
• Enhanced Nether Portals with a cinematic purple-blue appearance.
• Increased the portal’s nearby colored-light contribution.
• Adapted Nether Storm intensity and color to each biome.
• Added denser gray ash in Basalt Deltas.
• Reduced storm intensity in Warped Forests and Soul Sand Valleys.

🍎 macOS Compatibility

• Added a dedicated compatibility path for Apple’s OpenGL driver.
• macOS temporarily uses the complete Nether rendering path from v1.3.7.
• This prevents the native libGLProgrammability.dylib compiler crash.
• The Nether remains stable and visually consistent on Mac.
• New Nether effects remain available on Windows and Linux while macOS compatibility is improved gradually.

🛠️ Fixes and Stability

• Removed unsafe Nether density calculations from global shader scope.
• Restricted Nether-specific calculations to Nether programs.
• Added platform-specific guards for Apple OpenGL.
• Preserved Distant Horizons compatibility.
• Prevented historical shader copies and unwanted files from entering releases.
• Added protection against invalid settings, broken includes and unsafe defaults.

✅ Automated Validation

• Validated 379 shader files.
• Checked 723 shader includes.
• Verified all 399 files in the downloadable package.
• Validated JSON metadata and balanced GLSL delimiters.
• Checked shader menus, sliders and default values.
• Tested preprocessor structures and platform-specific compatibility paths.
• Confirmed that no .DS_Store or unwanted ZIP files are included.

🌍 Compatibility

• Minecraft Java Edition 1.8 through 26.2.
• Iris Shaders.
• Compatible OptiFine versions.
• Distant Horizons support.
• Windows, Linux and macOS.

The Overworld remains visually unchanged in this release, allowing v1.3.8 to focus entirely on improving the End, renewing the Nether and strengthening cross-platform stability. 🚀
