What it changes Lighting follows a natural day cycle. Morning and evening are orange, noon is white-blue, and night is blue, with deeper blue shadows. Torch and block light are bright up close and fall off quickly. Colors lose saturation in darkness, at night, and in rain. Exposure is fixed, not automatic: day stays readable, and night, caves, and rain get a small boost. The End is left as before. The Nether takes its light color from the biome fog. The sky has a shaded sun and moon that redden near the horizon, with real moon phases. Night stars are brighter and denser, meteors appear sometimes, and snowy biomes can show a green-blue-purple aurora at night. Version 3.1 fixes a white sheet behind the horizon. Minecraft’s sky dome used to stop a little above the horizon, so fog color showed through as a blank white band. The dome is now drawn below the horizon and filled with the shader’s own horizon color. Below the horizon the sky is no longer mirrored, and clouds are only calculated above it. Clouds are volumetric and drawn on the sky dome, not on vanilla cloud cubes. The default style is a layered, puffy look. A second style is available, plus the older LiteCraft mesh clouds (style 50) and plain vanilla clouds (style 0). They react to clear weather, rain, thunder, snow biomes, and dry biomes, and blend into one gray sheet in rain. Fancy clouds in the video settings are not required for the volumetric styles. Water has fine waves from a noise texture, optional parallax, surface motion, its own color and transparency, water fog, sun and moon glints, and underwater distortion. Sky reflections use a Fresnel term and show only the LiteCraft sky, without clouds or aurora. Refraction, screen-space reflections, caustics, and colored water shadows are left out on purpose, because they need extra passes. Other effects: soft sun and moon shadows, waving grass, crops, and leaves, rain streaks with a glass-like highlight and a little wind drift, snow sparkle in direct sun, light rays through trees and fog (stronger and bluer underwater), a light vignette, optional motion blur, and glowing mob eyes — enderman purple, spider red, phantom green.
