What's new

Version 1.0.0 (Initial Release)

🌟 Core Features

  • Path-Traced Core Engine: Implemented full 3-bounce global illumination (GI) for indirect lighting in caves, structures, and heavy forest canopy.

  • Spectral Glass & Gem Refraction: Added light dispersion through stained glass, diamonds, emeralds, and ice.

  • Adaptive Volumetric Fog: Introduced altitude-based fog layer density with dynamic sunbeam scattering (god rays).

💧 Water & Surfaces

  • Built custom physical-based rendering (PBR) water shaders with realistic depth absorption and shore foam generation.

  • Added wetness shaders for ground blocks during and after rainstorm weather events.

  • Integrated parallax occlusion mapping (POM) support for 16x to 512x resource packs.

🌙 Atmosphere & Skybox

  • Custom night skybox featuring procedural auroras (enabled automatically in cold biomes).

  • Dynamic point-light shadows for torch, redstone lamp, and glowstone block illumination.

⚙️ Performance & Optimization

  • Implemented Temporal Anti-Aliasing (TAA) combined with dynamic fidelity scaling to maintain stable frame rates on mid-to-high tier GPUs.

  • Added granular profiles: Performance, Balanced, Ultra, and Cinematic PTGI.
