Aster

Aster is an all-in-one shader pack for Iris. It aims to look as good as possible while staying fast

The sky

A full night sky: thousands of twinkling, coloured stars, the Milky Way, nebulae, distant galaxies and planets
Shooting stars, fireballs, meteor showers and rare comets
Auroras, sun halos and rainbows after rain
Warm sunrises and sunsets, drifting clouds and a glowing moon
A custom End sky

Light and shadow

Soft, clean shadows
Coloured shadows through stained glass
Sun rays and god rays through trees
Leaves and grass that let sunlight through
Coloured light: torches glow orange, soul fire blue, sea lanterns pale blue, and stained glass tints the light that passes through it

Water

Reflections of the sky and the world around it
Animated waves, and streams and waterfalls that visibly flow
Underwater light rays, and moving spots of sunlight on the bottom where those rays land

Weather

Thin, realistic rain streaks and custom snowflakes
Wet ground and walls that darken and shine in the rain
Dark storm skies, sheet lightning in the clouds and custom lightning bolts that light up the world

Every dimension

Nether: warm, moody lighting and fog that take their colour from the biome, with glowing lava and fire
The End: purple-lit islands under a starry End sky, with a soft haze

Also included

Waving grass, leaves, flowers and vines
Bloom, temporal anti-aliasing and a filmic tone map
Low, Medium, High and Ultra presets, plus a menu with clear descriptions for every option

Requirements

Minecraft Java Edition with Iris (Sodium recommended)
Works on Windows and macOS. On Mac, coloured light is turned off because macOS does not support the compute shaders it needs; everything else works.

Installation

Install Iris (and Sodium).
Put the downloaded Aster.zip into .minecraft/shaderpacks/. Don’t unzip it.
In game, open Options → Video Settings → Shader Packs and select Aster.

Performance tips

Start with the Medium preset and go up or down from there.
The options that cost the most are Shadow Quality, Shadow Distance, Sun Rays and Coloured Light.
