Expanse Shaders
Lightweight shaders for Iris that keep vanilla's soul but give every dimension its own air. Built alongside the End Expanse mod — the pack knows its plants and crystals — but works standalone everywhere.
☀️ Overworld
- Soft PCF shadows from sun and moon (rotating-kernel penumbra, night shadows included)
- Procedural sky: gradient dome, sun halo, peach sunsets, moon glow, rain wash
- Waving leaves, grass, crops and flowers
- Water with irregular waves, sky reflection and sun glint
- Underwater: murk, darkening and crepuscular light shafts
🔥 Nether
- Rolling steam: luminous mist banks in the biome's color drift between the rocks in real time
- Lava and magma slowly shimmer as if molten rock moves under the crust
- Fixed world-space form shading keeps depth under the bedrock roof
🌌 The End
- Aurora curtains drifting overhead in teal and violet, with vertical light pillars on the horizon
- The aurora casts a slow breathing light wash onto the islands
- Abyss fog: the void below the islands darkens and thickens
- Occasional meteors streak across the star field
✨ Everywhere
- Bloom around light sources; torches, glowstone, chorus flowers and lava keep full brightness
- Two-layer atmosphere: a near veil around the player plus optional distant haze
- Filmic tonemap with protected shadows, saturation and exposure controls
- Three presets (Low / Medium / High) and a fully localized settings screen (English / Русский)
Tested on Iris 1.9+ (Minecraft 1.21.x). No Sodium conflicts — Iris runs on Sodium.

Лёгкие шейдеры для Iris в духе ванили: мягкие тени днём и ночью, блум и свечение источников света, качающаяся листва, живая вода с подводными лучами, движущийся пар в Незере, северное сияние с метеорами над Эндом и двухслойная атмосферная дымка. Три пресета, все настройки переведены на русский. Создан в паре с модом End Expanse, но полноценно работает и без него.
