NaturalVision Shaders

v1.1.0 — The True Vision Update

New

• True retinal adaptation: fast light-adaptation, slow dark-adaptation (like real photoreceptors), with pupil-coupled depth of field
• Screen-Space Contact Shadows (SSCS)
• Film daylight model: hemispheric sky fill + warm ground-bounce fill light
• Real twilight optics: blue hour, violet band, Belt of Venus, Earth's shadow
• Realistic aurora curtains with ray striations and true emission colors
• 15 detail features: snow sparkle, emissive ores, molten glow, torch flicker, rain ripples, puddles, waterfall foam, underwater bubbles, moon halo, star twinkle, cloud-gap god rays, cinematic letterbox & more
• Rain-on-lens impact system: drops pop on hit, dry in ~1.5s, follow where you look

Improved

• Water rebuilt with real Fresnel: transparent looking down, mirror at grazing angles; calm glass waves
• Multi-scale volumetric clouds (no more repeating pattern)
• Major optimization pass (SSGI distance cutoff, cheaper depth math, smarter SSR)
• Compatibility widened: MC 1.19.1 → 26.x, any Iris + Sodium, OptiFine G9+

Fixed

• Pink streaks in daytime water reflections
• Sun/moon disc visible during storms
• "Rising smoke" artifact in rainy skies
• Ores now glow properly in the dark
• Stability: NaN guards, DOF focus cl
