Lumina Shader - Lite

🌌 Lumina Shader Lite v1.2.6 This maintenance update makes Lumina Shader Lite more stable in difficult rendering conditions while preserving its lightweight design and visual identity. ✨

🛠️ Fixed — Rendering Stability 🛡️ Prevented black rectangles around enchanted armor and players by safely discarding near-transparent fragments. 🌤️ Prevented invalid NaN values in natural and ice light shafts when shadow colors have no length. ☁️ Stabilized cloud-shadow projection when the sun aligns with a horizontal world axis. ❄️ Protected biome-tint removal from division by zero on snowy terrain, leaves, and IPBR materials. 💧 Prevented high water-wave settings from producing invalid normal-map calculations. 🌫️ Protected Lightshaft Smoke from division by zero in empty volumetric samples.

🎨 Improved — Compatibility & Interface 👻 Preserved intentionally translucent modded entities while still discarding fully transparent fragments. 🎛️ Removed unavailable Advanced Color Tracing controls from the Lite interface and profiles.

✅ Validation 🔍 Version checks now require exact metadata matches and reject incorrect pre-release suffixes. 🤖 Added automatic shader validation for development pushes, main, and pull requests. 📦 Verified shader includes, preprocessor blocks, default profiles, metadata, and ZIP/source parity. 🧹 Confirmed that the final ZIP contains 397 files with no unnecessary macOS metadata.

💙 Thank you for using Lumina Shader Lite! Enjoy a cleaner, safer, and more stable visual experience.

🌌 Lumina Shader Lite v1.2.5

This update improves the sky, emissive lighting, visual customization, and stability while preserving Lumina Shader Lite’s lightweight design and performance-first philosophy. ✨

✨ Added 🌠 Milky Way Brightness Added a new Milky Way Brightness setting under Environment & Sky. Available levels: OFF, 25%, 50%, 75%, 100%, 125%, and 150%. The default value is 100%, preserving the original appearance. Selecting OFF removes the Milky Way calculations from both the sky and reflection shaders, providing a small performance improvement. 🌋 Lava Brightness Added an independent control for adjusting lava brightness. Players can now reduce or increase lava intensity without changing other emissive materials. 🎨 Visual Improvements ☀️ The daytime horizon and distant atmospheric fog now use a cleaner, more natural sky-blue tone. 🌌 The Milky Way now follows the movement of the night sky correctly. 🔭 Improved the continuity of the Milky Way’s procedural pattern to prevent visible seams. 🌧️ Corrected the middle-sky coloration during heavy rain when using the Heavy & Colder weather style. 🌋 Improved the balance of lava emission and bloom.

🛠️ Fixed Prevented large lava surfaces from overexposing the image and washing the screen out to white. Limited lava emission before it enters the Bloom pass. Added a safety limit to the Bloom input to control extreme emissive sources. Fixed an inherited bug that used the horizon rain color for the middle portion of the sky. Applied the rainy-weather color correction both with and without SPECIAL_BIOME_WEATHER. Removed the spherical-coordinate seam from the Milky Way. Corrected the Milky Way’s celestial orientation so it moves naturally with the night sky.

⚡ Optimized Reduced the number of procedural noise calculations used by the Milky Way. The Milky Way continues to use no additional textures, ray marching, or expensive volumetric effects. Disabling the Milky Way completely excludes its calculations from the compiled sky and reflection shaders. The default 100% setting preserves the intended appearance and Lumina Shader Lite’s performance-focused identity.

✅ Validation Validated shader references and includes. Verified every conditional path used by the new options. Validated the settings menu and every available value. Verified distribution-package integrity and source parity. Confirmed that the final ZIP contains 397 files. Confirmed that no unnecessary macOS metadata, including .DS_Store, is present.

💙 Thank you for using Lumina Shader Lite! Enjoy brighter skies, better lighting, improved customization, and smooth performance.

Lumina Shader Lite v1.2.4 combines the validated RC4 visuals with the internal fixes and optimizations tested throughout the release-candidate cycle.

Added:

Wide diagonal Milky Way with rounded galactic clouds, warm core, cool outer haze and a warped dust lane. Fixed:

Prevented NaN values during zero-luminance color normalization. Corrected Distant Horizons temporal reprojection to reduce LOD ghosting. Removed directional streaks from the Milky Way while preserving the dark midnight sky and existing stars. Optimized:

Reused lightmap power calculations during shadow sampling. Milky Way uses no texture samples, new assets or volumetric ray marching. Validation:

Added automated metadata, include, preprocessor, profile and ZIP/source parity checks.

Final visual release candidate. This updates RC4 in place; no RC5 was created.

Fixed:

Removed the remaining fiber/curtain pattern caused by projecting pixel noise across the sky. Changed:

Uses Lumina’s existing smooth cloud texture for coherent galactic masses. Two independently rotated layers form the wide glow and irregular dust lane. Preserves the diagonal arc, cool outer haze, warm core and dark midnight background. Performance:

Reduced from three texture samples to two. No new assets, iterative noise loops or volumetric ray marching.

Visual test candidate replacing the overly subtle RC2 Milky Way.

Changed:

Wider and substantially more visible galactic arc. Irregular luminous clouds and fine-scale structure. Warm, concentrated galactic core. Warped central dust lane inspired by real Milky Way photography. Performance design:

Reuses the existing shader noise texture. Three texture samples only. No iterative procedural-noise loops or volumetric ray marching. Please test at midnight in clear weather and compare visibility near the horizon and zenith.

Visual test candidate based on RC1.

Added:

A subtle, naturally tilted Milky Way band while preserving the dark midnight sky and current stars. A lightweight central dust lane and gentle structural variation. The same subtle band in eligible high-quality sky reflections. Performance design:

No additional texture samples. No loops or volumetric noise. Uses a small analytic calculation and fades out during rain, daylight and obstructed visibility. Please test at midnight from open terrain, looking from horizon to zenith, with and without rain.

Candidate for in-game testing before the stable v1.2.4 release.

Fixed:

Prevents NaN values during zero-luminance color normalization. Corrects Distant Horizons temporal reprojection to reduce LOD ghosting during camera movement. Optimized:

Reuses lightmap power calculations during shadow sampling. Please test dark scenes, camera movement near Distant Horizons LOD transitions, and shadows across the performance profiles.

Changelog 1.2.3 - 2026-07-13 Lumina Shader Lite 1.2.3 is a maintenance release focused exclusively on bug fixes. It does not introduce intentional visual changes or new features.

Fixed Corrected vertical image-sharpening offsets on non-square resolutions. Replaced undefined reversed smoothstep calls in dark-color tonemapping. Corrected the Distant Horizons water fade to behave consistently across GPU drivers. Removed invalid GLSL text from the reserved composite2 program. Centered the final dithering noise to prevent a small positive brightness bias. Added the missing default profile mapping so the active defaults are identified correctly. Removed the incorrect "Default" label from the High profile.
