Requirements

  • Forge 1.20.1 + Embeddium + Oculus — developed and tested with Forge 47.4.10, Embeddium 0.3.31 and Oculus 1.8.0.
  • Fabric 1.20.1 + Sodium + Iris — should work (Oculus is a port of Iris and the pack only uses Iris features), but it has not been tested on Fabric yet. Reports are welcome!
  • OptiFine is not supported.

Installation

  1. Download the .zip and put it without unzipping into .minecraft/shaderpacks/.
  2. In game: Options → Video Settings → Shader Packs → Cristal Shaders.
  3. Open Shader Pack Settings and choose a profile: Low, Medium (default), High or Ultra.

What it changes

Water

  • Clear water where you can see the bottom, turning deeper turquoise with depth.
  • Screen-space reflections of the sky, clouds and shore, with a mirror-like look on calm water.
  • Refraction, animated caustics on the bottom, and white foam along shorelines.
  • Underwater light shafts, and raindrop ripples on the surface (visible from above and below).
  • Wet screen: after leaving water, a sheet of water ripples across the screen and drains away.

Light and shadows

  • Warm golden sunlight with cool shaded areas, ACES tone mapping and soft bloom.
  • Soft PCF shadows (PCSS penumbra on High/Ultra) and colored shadows through stained glass.
  • God rays through leaves, with optional floating dust motes.
  • Colored block light: torches light orange, soul lanterns light blue, and so on.
  • Held light sources light up your surroundings.
  • Dark, moody caves.

Sky

  • Round sun and a moon with craters and real moon phases.
  • Thousands of colored, twinkling stars and a Milky Way.
  • Volumetric cumulus clouds with silver linings, plus high cirrus and altocumulus layers.
  • Cloud cover changes from day to day: clear days and cloudy days.

Weather and atmosphere

  • Rain puddles that reflect the sky and surroundings, with raindrop ripples, which dry slowly afterwards.
  • Wet ground that darkens in the rain, and sun sparkles on it once the sun comes back.
  • Lightning that lights up the whole landscape.
  • Rainbows after rain, dawn mist over valleys and rivers, auroras in snowy biomes at night.
  • Fireflies on summer nights, and snow that builds up on blocks while it snows.
  • Plants and leaves sway in the wind, harder during storms.

Caves, Nether and End

  • Glowing ores that softly light the surrounding rock with their color.
  • Molten lava in orange and yellow with slowly flowing currents, glowing on nearby walls, with heat haze above it.
  • Warm, hazy Nether atmosphere.
  • Living Nether portal: swirling energy with depth, sparks, a glowing edge and a vortex when you step in.
  • Living End portal: a window into space with nebulae and stars, plus glowing Eyes of Ender.
  • End sky with nebulae and stars.

Clean glass

  • Removes the frame and streaks from vanilla glass, with real reflections and slight distortion.

Performance

Low Medium High Ultra
Shadows 1024 / 64 blocks 2048 / 96 3072 / 160, PCSS 4096 / 256, PCSS
Volumetric clouds off 16 steps 24 steps 32 steps
Reflections sky only 12 steps 16 steps 32 steps

Medium runs at about 45–55 FPS on an RTX 3050 Laptop GPU at 1080p. Use High or Ultra on a stronger GPU.

Settings

The main settings screen keeps only the essentials: brightness, color vibrance, daylight warmth, clouds, water clarity, wind, ore glow, lava style and wet screen. Everything else is under Advanced, grouped by topic. Almost every effect can be turned off or tuned. The menu is available in English and Spanish.

Known limitations

  • Auroras, lightning flashes and snow accumulation rely on data provided by Iris/Oculus. On very old Oculus versions they may simply not appear.
  • The pack draws its own clouds, sun and moon, so resource-pack textures for those won't show while it is active (each one can be switched off).
