Zepholume Shaders V1.0.1

File: Zepholume-Shaders-1.0.1.zip

A major visual refinement and optimization update focused on making Zepholume more atmospheric, consistent, stable, and efficient without turning the shader pack into a GPU furnace. 🔥

✨ Visual Improvements

• Reworked sun elevation and twilight transitions for smoother lighting throughout the day.
• Improved sky and horizon rendering with more natural atmospheric coloration.
• Refined sun and moon glow for a cleaner, less artificial appearance.
• Improved sunrise and sunset tones with restrained warmth instead of excessive orange tinting.
• Better integration between sky, terrain, clouds, and fog.
• Improved rainy-weather desaturation and atmospheric response.
• Refined Overworld fog for better depth and scene readability.
• Improved Nether and End atmosphere while preserving dimension identity.
• Improved cloud coloration and environmental blending.

🌊 Water Improvements

• Added subtle real-time animated water movement on supported quality profiles.
• Water animation now responds to frame time instead of relying on static pseudo-movement.
• Kept the effect deliberately lightweight to preserve Zepholume's performance-focused design.

⚡ Performance & Optimization

• Reduced unnecessary shader work across several rendering paths.
• Potato mode now compiles out additional analytical sky and cloud calculations.
• Maintained genuine compile-time differences between quality profiles instead of merely changing cosmetic values.
• Removed a redundant display-linear decoding operation.
• Preserved Zepholume's lightweight architecture:
  • No shadow maps
  • No SSR
  • No SSAO
  • No volumetric lighting
  • No temporal buffers
  • No compute shaders
  • No expensive post-processing pipeline

🛡️ Stability & Compatibility

• Added safer vector normalization to prevent potential NaN rendering errors caused by malformed or unusual geometry.
• Improved handling of modded and unusual rendering inputs.
• Continued portability work for NVIDIA, AMD, and Intel GPUs.
• Improved common-denominator compatibility between Iris and Oculus.
• Preserved vanilla texture detail, transparency, entities, particles, hand rendering, and modded-content visibility.

🔧 Internal Improvements

• Unified several lighting and atmosphere calculations for more consistent rendering.
• Cleaned up redundant shader operations.
• Strengthened profile-specific compilation behaviour.
• Improved shader validation and defensive rendering logic.

📌 Requirements

Zepholume Shaders requires a compatible shader loader such as Iris Shaders or Oculus.

Minecraft Java 1.20+ versions are the currently tested target. Older Minecraft versions may work, but compatibility is not guaranteed.

Zepholume Shaders V1.0.1 is primarily about refinement: better atmosphere, smoother environmental transitions, improved stability, and smarter performance without abandoning the lightweight philosophy of V1.0.0.
