Horizon Shader

HORIZON SHADER
v1.0.1 (update)
Platforms: Windows (1.26.51+), Android (1.26.52)
New
Snow / ice: rain ripples, puddles and wet reflections are turned off on snow and ice blocks; a soft snow sparkle shows instead.
Ice and packed ice: glassy reflection of the landscape, soft clouds and the sun.
Water: sun reflection upgraded - new tight glitter on animated waves, in the correct direction towards the sun, golden at sunrise/sunset.
Rainbow: appears only on some days, with a soft fade in and out.
Clouds: distant clouds fade into the horizon haze (atmospheric perspective).
Sunrise / sunset sky colours are warmer and more golden; terrain fog matches the sky.
Fixed
Clouds: stutter / jumping when moving towards or into the cloud layer.
Clouds: dots on the cloud edges are evenly spread and blend together.
Rain ripples: sun glint on ripples now follows the real sun direction.
Performance
Cloud ray-march: 3 steps, light is calculated once per pixel, cheaper when the camera is near or inside the cloud layer.
Torch glint on water is off.
Android: phone mode - same look as Windows but cheaper (fewer noise lookups in water sun reflection, cheaper ice reflection, lighter cloud detail range), made to run on low-end phones.
Unchanged
Aurora (aurora subpack), player 3D shadow, metal reflections.
Known limits
Rainbow cannot know when rain ended (a shader has no memory); it shows during the game's own rain fade.
Snow detection is by block colour (the shader does not know the biome).
