Lumina Shader - Lite

🌟 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.

Lumina Shader: Lite v1.2.1 - Ultimate Optimization

1. Brand & Credits

Main Developer: Benjiaa is now officially established as the Lead Developer.

UI Cleanup: Simplified the "Information" menu by removing social links for a faster, cleaner experience.

2. Extreme Performance Boost ⚡

Ultra-Fast Shadows: Shadow resolution and distance have been further tuned to ensure maximum FPS on low-end PCs and integrated graphics.

Efficient Lighting: Simplified Volumetric Lighting and SSAO passes to maintain the "Lumina look" without the performance cost.

Optimized Reflections: Water and surface reflections have been streamlined for maximum efficiency.

Lumina Lite v1.1.1 — The Stability & Precision Update ⚡

This update brings critical technical fixes and performance balancing to ensure Lumina Lite runs flawlessly on all hardware.

✨ Visual Improvements Shadow Precision Tuning: Optimized shadow depth precision (0.3). This fixes "Peter Panning" (floating shadows) and ensures shadows remain sharp and stable as you move through the world.

End Dimension Lighting Fix: Implemented radial lighting in the End. Blocks and entities now have proper depth and volume in the dark dimension.

🚀 Performance & Optimization Optimized God Rays: Volumetric lighting samples have been adjusted to 12 samples. This maintains the cinematic look while providing a significant FPS boost for low-end GPUs.

Internal Cleanup: Stripped unused colored lighting logic when disabled to reduce GPU overhead.

🛠️ Bug Fixes & Compatibility Distant Horizons Fix: Removed water elevation offsets to prevent Z-fighting (flickering) when using the Distant Horizons mod.

Stability Patch: Fixed minor glsl syntax issues for better compatibility with newer Iris/Oculus versions.

Lumina Lite v1.1.0 - Performance & Clarity Update

The first major update for the Lite version is here! We've focused on making the shader even faster for low-end PCs while improving the overall look.

🚀 Performance Improvements:

• Optimized God Rays: Drastically reduced internal sample count. You will see a significant FPS boost, especially during sunrise and sunset.
• Efficient Clouds: 3D clouds have been re-tuned to be lighter on your GPU.
• Optimized TAA: New Anti-Aliasing configuration that is faster and reduces ghosting/blurriness.

🎨 Visual Enhancements:

• Neutral Color Calibration: Implemented a new 6500K White Balance. The world no longer looks yellowish; colors are now natural and vibrant.
• Better Exposure: Fixed the brightness levels (Exposure 1.15) so the world looks clear even on the darkest days.

🛠️ Technical Details:

• Full 1.21+ Support: Updated pack_format to 34 for full compatibility with the latest Minecraft versions.
• Official Version: This is the ONLY official and original Lumina Shader project.
