🚀 Lumina Shader Lite v1.2.7 — Performance Unleashed

Lumina Shader Lite is now faster, cleaner, and more efficient than ever. ⚡

This major performance-focused update completely reworks every quality profile, significantly reduces unnecessary GPU work, and improves the experience on integrated and low-end graphics—while preserving the visual identity of Lumina Lite.

Internal testing showed an impressive 28–30% increase in FPS, depending on the hardware, profile, and scene. 📈

⚡ Massive Performance Improvements

• Completely optimized all seven performance profiles, from Potato to Ultra.
• Reduced the cost of shadows, reflections, SSAO, bloom, water, clouds, and entity shadows.
• Prevented unused reflection and post-processing passes from running on lower profiles.
• Disabled inactive Temporal Anti-Aliasing programs when they are not required.
• Reduced low-detail bloom filtering from 49 to 25 samples per active tile.
• Reduced low-detail procedural water normals from four texture reads to two.
• Improved shader activation times on Low, Very Low, and Potato.
• Significantly improved performance on integrated graphics and low-end GPUs.

🎚️ Completely Rebalanced Profiles

Every profile now follows a clear and consistent quality ladder:

🥔 Potato → Maximum performance
⚡ Very Low → Lightweight visuals
🚀 Low → Best performance-quality balance
🎮 Medium → Improved effects and detail
✨ High → Higher shadows and visual quality
💎 Very High → Advanced effects
🌟 Ultra → Maximum visual quality

Low is now the default profile, providing smoother performance, lower GPU usage, and a better experience immediately after installing the shader.

The inherited Complementary profile has been removed, making the profile selector cleaner and preventing confusing or incorrect default settings.

🌕 New Configurable Moon Halo

The Minecraft night sky receives a beautiful new atmospheric detail:

• Added a soft procedural halo around the Moon.
• Fully configurable intensity.
• Automatically reacts to rain, clouds, and lunar phases.
• Appears naturally in eligible sky and water reflections.
• Uses no additional textures or expensive volumetric effects.
• When disabled, its code is completely excluded from compilation.

The result is a more cinematic and immersive night sky without sacrificing Lumina Lite’s lightweight design. 🌌

🌊 Water and Visual Fixes

• Fixed water compilation errors affecting Potato, Very Low, and Low.
• Improved the stability of low-detail procedural water.
• Added safer custom normal-map reconstruction for labPBR resource packs.
• Stabilized PBR and POM displacement calculations.
• Improved GGX reflections at extreme viewing angles.
• Protected cloud-shadow calculations from invalid angles.
• Added safer anisotropic-filtering fallbacks.
• Fixed mathematical instability in pixelated rainbows near the horizon.

🧹 Cleaner Interface

• Removed obsolete Advanced Color Tracing controls.
• Removed unavailable World-Space Reflections options.
• Eliminated inherited and orphaned settings screens.
• Simplified the optimization menu.
• Improved profile consistency and default-value handling.

🧪 Stronger Automatic Validation

Lumina Shader Lite now automatically validates:

• Performance-profile order and safeguards.
• Menus, options, screens, and sliders.
• Lightweight shader program paths.
• Metadata and version consistency.
• Shader includes and conditional blocks.
• Release ZIP integrity and source parity.
• Invalid, duplicated, hidden, or obsolete controls.

These checks help prevent configuration mistakes and performance regressions in future updates. 🛡️

📈 The Result

• Up to 28–30% higher FPS in testing.
• Faster shader activation on lower profiles.
• Lower GPU usage in expensive scenes.
• Better performance on integrated graphics.
• More consistent quality progression.
• Improved water and PBR stability.
• Cleaner menus and safer configuration.
• A beautiful new Moon halo with minimal performance cost.

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.

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.

🌟 Lumina Shader: Lite Edition — v1.2.2 Changelog
🌤️ 1. Cloud Shadow Optimization (Community Feedback)
Disabled by Default: Commented out the #define CLOUD_SHADOWS directive in the global configuration file (common.glsl).

The Fix: Resolves a community-reported issue (highlighted by creators on TikTok) where cloud shadows appeared too blocky or harsh for a lightweight shader. Disabling this by default saves a massive solar light calculation pass, significantly boosting baseline performance (fully toggleable in the settings menu).

🌊 2. Premium Water Overhaul ("Butter Shader" Style)
Smooth Stylized Base: Completely removed the pixelated vanilla Minecraft texture grid (colorP.rgb). Replaced it with a sleek, flat, and modern look inside water.glsl (colorPM = vec3(0.35)).

Vibrant Turquoise Glow: Tweaked the biome-specific coefficients (glColorM) to a stunning turquoise/cyan tint (vec3(0.85, 1.08, 1.32)) and amplified its emission brightness to 0.55 * glColorM for a glowing, crystal-clear tropical look.

Parallax Displacement Bypass (Massive FPS Save): Disabled the heavy ray-marching relief loop (#if 0), cutting down 8 texture lookups per pixel to guarantee blazing-fast rendering speeds on integrated GPUs.

Sleek Gloss Speculars: Unified specular reflections to a high smoothness value of 0.55 (smoothnessG), delivering clean, cinematic sun/moon reflections on the water surface instead of pixelated noise.

Compilation Safety Guard (30 FPS Restored): Wrapped advanced normal mapping calculations inside a safe conditional block (#if WATER_STYLE >= 2). This fixes a critical shader compilation warning/bug on low-end profiles, instantly restoring up to 30 lost FPS.

Uniform Opacity: Set water alpha transparency to a polished 0.52 value for maximum underwater visibility and clean depth blending.

🌌 3. Vibrant & High-Saturation Skies
Redesigned all atmospheric color profiles inside skyColors.glsl to eliminate the default washed-out look and provide punchy, high-contrast skies:

☀️ Daytime: Shifted the upper sky to a rich indigo (vec3(0.68, 0.82, 1.15)) and the mid-sky to a bright, summery cyan (vec3(1.15, 1.3, 1.45)).

🌅 Sunset (Golden Hour): Adjusted the horizon to a majestic amber-gold (vec3(1.70, 0.80, 0.30)), the mid-layer to a fiery orange (vec3(2.1, 1.20, 0.80)), and the upper twilight to a beautiful orange-magenta gradient (vec3(0.75, 0.40, 0.60)).

🌙 Nighttime: Configured the night sky blend into a deep, aesthetic indigo-midnight blue (vec3(0.03, 0.09, 0.24)).

📦 4. Deployment & Build Cleanup
Version Sync: Officially bumped the shader versioning to v1.2.2 across both project metadata (pack.json) and the localization interface strings (en_US.lang).

Clean Packaging: Generated the final deployment archive, wiping out all temporary developer cache and unoptimized asset residues.
