Zepholume Shaders V1.0.4

Changes

• Optimized the water celestial-specular path with exact-zero gating.
  • Expensive sun/moon specular calculations are now skipped when their contribution is exactly zero.
  • Keeps the existing water appearance and lighting behaviour unchanged when the effect is active.
• Improved shader hot-path efficiency without adding new rendering features or visual complexity.
• Preserved the lightweight rendering design:
  • No shadow maps
  • No SSR
  • No SSAO
  • No volumetrics
  • No temporal effects/TAA
  • No compute shaders
  • No additional colour buffers

Validation & Stability

• Retained the V1.0.3 visual and mathematical behaviour outside the targeted optimization.
• Revalidated shader compilation and portability checks.
• Regression tests continue to cover important lighting, transition, and numerical behaviour.
• Deferred a proposed fog optimization because its benefit was not sufficiently proven.

Notes

V1.0.4 is primarily a targeted optimization and maintenance release. It deliberately avoids speculative optimizations that could increase complexity or introduce visual regressions.

Actual runtime performance improvement can vary by GPU, driver, Minecraft configuration, shader profile, and scene.
