Cristal Shaders

Cristal Shaders is a shader pack for Minecraft Java 1.20.1 built around crystal-clear water, warm natural light and skies that change every day. It runs on Oculus (Forge) and is designed to stay smooth on mid-range laptops.

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.
• OptiFine is not supported.

Installation

1. Put the .zip 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.

Features

Water

• Clear water with a visible bottom.
• Reflections of the sky and shore.
• Refraction and animated caustics.
• Shore foam and underwater light shafts.
• Raindrop ripples on the surface.
• A wet-screen ripple when you leave the water.

Light and shadows

• Warm golden sunlight with ACES tone mapping and soft bloom.
• Soft shadows (PCSS on High and Ultra) and colored shadows through stained glass.
• God rays through leaves.
• Colored block light, and held light sources that light up your surroundings.

Sky

• Round sun and a moon with real phases.
• Thousands of twinkling stars and the Milky Way.
• Volumetric cumulus clouds, plus cirrus and altocumulus layers.
• Cloud cover that changes from day to day.

Weather and atmosphere

• Rain puddles that reflect the sky, and wet ground with sparkles once the sun returns.
• Lightning that lights up the landscape.
• Rainbows, dawn mist, auroras in snowy biomes, fireflies and snow accumulation.
• Plants and leaves that sway in the wind.

Caves, Nether and End

• Glowing ores that light the surrounding rock.
• Molten lava with flowing currents and heat haze.
• A warm, hazy Nether.
• Animated Nether and End portals, and an End sky with nebulae.

Performance

Medium runs at about 45–55 FPS on an RTX 3050 Laptop GPU at 1080p. High and Ultra raise shadow, cloud and reflection quality for stronger GPUs. Almost every effect can be turned off or tuned in the settings, which are available in English and Spanish.

Known limitations

• Auroras, lightning flashes and snow accumulation rely on data from Iris/Oculus. On very old Oculus versions they may 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 can be switched off).

How it was made

Cristal Shaders was designed, directed and tested by Eiden, who decided the look of every effect, compared it against other shaders and tested each version in game. The shader code and this description were written with Claude, an AI model by Anthropic, following his direction. All gallery screenshots and the icon are real in-game captures. Third-party code (MIT licensed) is credited in CREDITS.txt.
