Added

  • New settings window built with Arkea: pages, presets, search, previews and a GPU impact meter
  • Initial mod setup for Minecraft 26.3 on NeoForge
  • Vulkan render core that draws the whole world through Helion's own stages with a picture identical to vanilla
  • Own color and depth buffers for the world image
  • Automatic fallback to vanilla rendering on OpenGL, with Sodium or Iris, or after a rendering error
  • Toggle key (H) to switch between Helion and vanilla rendering
  • Debug mode that shows every Helion value on screen, logs it as JSON and runs the parity check with the J key
  • Parity check image that marks every differing pixel, plus a warning when the game was not frozen during the check
  • Parity check that compares two frames from the same tick, so flickering torch light no longer counts as a difference
  • Settings screen with render core and debug mode options
  • Ambient occlusion with quality presets, strength, radius and a shadow-only view
  • Visibility bitmask ambient occlusion as an alternative method that keeps thin objects from casting dark halos
  • Experimental geometry buffer: terrain drawn by Helion shaders that also record normals, block light, sky light and base color
  • Experimental HDR lighting for terrain with separate block and sky light and intensity settings
  • Experimental temporal anti-aliasing that smooths block edges and distant textures
  • Experimental physical sky with spectral sky colors and fog that matches the sky in every direction
  • Experimental sun and moon shadows from blocks with quality presets
  • Bloom around bright light sources that adapts to daylight, caves and night, with intensity, threshold and a glow-only view
  • Neutral and Filmic tone mapping, exposure control and dithering against color banding
  • Optional contrast adaptive sharpening with a strength setting
  • English and Turkish translations

Changed

  • Adopt the Aryston Source-Available License
  • Draw the moon dimmer than the sun so it no longer glows like a second sun
