Zayko Shaders

Voxel Colored Lighting (Beta)

• Added real colored block light torches, glowstone, soul fire, sea lanterns, end rods and more tint their surroundings with true position and falloff
  • Added light that spreads around corners and keeps glowing even when the source is off-screen
    • Added smooth color mixing where different light sources meet (torch orange blending into soul-fire teal)
    • Changed the old Multicolored Blocklight into the fallback system (voxel mode replaces it when enabled)
      • enable it under Lighting > Voxel Colored Light (Beta)

Clouds

• Added a completely rebuilt cloud system. clouds now billow, bulge and overhang like real clouds instead of being flat.
  • Added a realistic cumulus profile: flat bases, full-bodied middles, and rounded billowing tops
    • Added an optional second high-altitude cirrus cloud layer for sky depth (Beta - off by default, enable it under Clouds)
    • Added cloud shadows on the ground (default on), god rays that break through cloud gaps, and lens flare that fades when the sun goes behind a cloud
      • Changed clouds to properly block what is behind them - sunlight and stars no longer shine through solid cloud
      • Changed backlit clouds to silhouette dark against the sun instead of washing out and disappearing
      • Changed cloud movement so shapes hold together and evolve slowly like real clouds, with brighter sunlit tops and shaded bases

Water

• Added the Glitter Path sun, moon, and star reflections now stretch
  • Added micro-ripples that catch sun glints without making the surface busy
    • Added optional refraction dispersion (subtle color fringes) and gradual rain wetness on surfaces
    • Changed depth coloring to true light absorption - water grades from clear shallows to deep opaque blue and reads properly deep from above
      • Changed waves to calmer, larger swells that move more naturally

Sky & Atmosphere

• Added the New Atmosphere (default on) physically inspired scattering with richer sunrises and sunsets, natural horizon haze, and a proper glow around the sun
  • Added Daily Weather Variety: every Minecraft day gets its own sky mood like clear days, streaky cirrus days, overcast days with morning fog banks
    • Added optional Volumetric Fog: rolling fog banks that sunbeams cut through
    • Changed fog and sunlight to always match the sky - distance haze blends into the horizon it fades into
      • Changed sunlight to warm realistically as the sun gets low

Customize Skybox

• Added the new Customize Skybox settings screen collecting all sky appearance options in one place
  • Added Sky Presets: Zayko, Golden, Violet Twilight, and Deep Night moods that shift sky, fog, and night lighting together
    • Added a much wider and finer Skybox Intensity range (0.05 to 4.00)
    • Changed Skybox Intensity and Skybox Opacity to actually work - resource-pack custom skies now show correctly instead of being overwritten
      • Changed vanilla sun/moon handling so they also display properly when shader sun/moon is disabled

Night Sky

• Added brighter, denser stars
  • Added smaller, faster shooting stars with tighter incandescent heads
    • Changed stars to render as crisp points - no more glow halos
      • Changed star visibility to respond to moonlight and weather

Color & Post-processing

• Added selectable Tonemap Operators: Zayko (classic), AgX, AgX Punchy, ACES, and Reinhard
  • Added the optional Purkinje night-vision effect and CAS sharpening
    • Changed bloom to a modern 13-tap filter - torch and star glow is visibly steadier and the pass is cheaper
      • Changed TAA with an anti-flicker refinement for specular sparkle

Lighting & Performance

• Added GTAO: an optional higher-accuracy ambient occlusion mode
  • Added AO Resolution and Light Shaft Resolution options (default Half - about 4x cheaper with near-identical visuals)
    • Added quality-profile coverage for all new features (Minimum through Ultra)
    • Changed the entire pack from 2006-era GLSL 120 to modern GLSL 330
      • Changed many internal passes to cost less (fewer texture fetches in bloom, cheaper volumetrics)

Fixes

• Fixed shader failing to load on Mac (two separate crashes: Distant Horizons with AO off, and the Overworld outline setup)
  • Fixed the washed-out white daytime sky from early V8 builds
    • Fixed Skybox Intensity/Opacity having no effect
    • Fixed clouds almost disappearing when in front of the sun
      • Fixed profile descriptions claiming features that were never enabled
