Lumina Shaders - Event Horizon

Lumina Event Horizon v1.3.7

Highlights

v1.3.7 establishes a fully independent cloud identity for Lumina Event Horizon. The inherited Reimagined and Unbound cloud styles have been replaced by one unified Lumina Clouds renderer with higher-resolution volumetric formations, improved lighting, more realistic shadows, and dedicated controls.

The release also expands the Event Horizon experience in the End with a dedicated settings menu, centralized rendering constants, corrected White Hole controls, and depth-aware energy-ray occlusion.

Lumina Clouds

• Replaced the inherited multi-style cloud selector with one unified Lumina Clouds renderer and visual identity.
• Rebuilt cloud formation using multi-octave volumetric density, height-aware erosion, anvil shaping, powder scattering, and silver-lining illumination.
• Increased medium and high ray-march resolution for smoother silhouettes and denser volume definition.
• Added dedicated controls for cloud coverage, formation scale, storm density, altitude, speed, color, and shadows.
• Removed the legacy secondary cloud layer, vanilla-cloud mode, and style-specific Reimagined/Unbound settings.
• Rebuilt terrain shadows from the same density, erosion, weather, scale, and wind model used by visible clouds.
• Projected cloud shadows toward the configured cloud layer along the active world-space light direction.

Event Horizon

• Added a dedicated Event Horizon Settings menu.
• Added controls for black-hole size, accretion-disk intensity, gravitational-lensing strength, disk rotation speed, the White Hole, and White Hole energy rays.
• Centralized Event Horizon direction, size, disk geometry, animation, and rendering constants.
• Aligned End lighting and post-processing with the centralized Event Horizon direction.
• Added depth-aware White Hole ray occlusion with softened terrain-edge sampling.
• Added White Hole ray occlusion support for Distant Horizons terrain.

Fixed

• Fixed the White Hole Rays toggle so Iris and OptiFine recognize it correctly.
• Fixed the closed-area cloud check so its shader option is recognized correctly.
• Prevented White Hole rays from rendering outside the viewport or through terrain.
• Removed the obsolete origin-facing End light fallback.
• Disabled cloud shadows automatically when cloud quality is set to Off.
• Removed an out-of-scope cloud-frequency reference that could break lighting-program compilation.
• Restored the valid shadow-map distance check used to hide clouds inside closed areas.
• Preserved the true first cloud-ray hit at close range for stable reflections and light shafts.
• Prevented undefined zero-vector normalization in opaque shadow and light-shaft colors.
• Added stable End light-direction handling at the exact world origin.
• Repaired invalid JSON metadata in the historical Event Horizon source copy.

Compatibility

• Minecraft Java Edition 1.8 through 26.2.
• Iris and compatible OptiFine shader loaders.
• Distant Horizons-aware cloud and White Hole rendering paths.

Validation

• Checked 379 GLSL, vertex, fragment, and compute shader files.
• Verified that every shader include resolves correctly.
• Verified balanced GLSL delimiters and valid JSON metadata.
• Tested cloud quality 0–3 across multiple scales and animation speeds.
• Tested White Hole and ray controls in all four On/Off combinations.
• Tested fragment and vertex variants with and without Distant Horizons.
• Validated all 399 files in the downloadable archive.
• Confirmed that the required license is included and no .DS_Store files are present.
• Confirmed that legacy Reimagined and Unbound cloud files are absent from the archive.
