🌟 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.
