Cristalino Shader

# Cristalino Shaders

**Cristalino** is a lightweight shader pack for **Iris** that makes Minecraft look realistic without the heavy FPS cost of big shader packs. Every material reflects light differently, glass is truly clear, and water looks and behaves like real water.

## ✨ Features

### 💧 Water
- Animated waves with real refraction
- Depth-based light absorption: shallow water is crystal clear, deep water turns blue-green
- Screen-space reflections with Fresnel (transparent when looking down, mirror-like at grazing angles)
- Sun and moon glints on the waves
- Caustics: dancing light patterns on the bottom
- **Underwater:** realistic color absorption, caustics, gentle view distortion, and a wavy view of the world above the surface

### 🪟 Glass, Gems & Ice
- Clear glass without the vanilla streaks, with an optional thin frame
- Clean stained glass using its average color
- **Translucent diamond, emerald, packed ice and blue ice blocks** (adjustable opacity)

### 🪞 Physically Based Materials
Each material has its own reflectivity and roughness:
- **Concrete:** soft satin sheen
- **Polished stone / quartz:** blurry, diffuse reflections
- **Glazed terracotta / obsidian:** near-mirror finish
- **Diamond:** high reflectance and sparkling sun highlights
- **Iron, gold, copper, netherite:** true metals that tint reflections with their own color

### ⚔️ Tools, Weapons & Armor
Items use the same materials as blocks. Only the part made of that material is affected: a diamond axe gets gem-like shine on its head while the wooden handle stays wood.

### ☀️ Lighting & Shadows
- Custom lighting: golden sunrises and sunsets, bluish shade, warm torchlight with natural falloff
- Soft, lightweight sun and moon shadows
- Handheld light: holding a torch lights up your surroundings
- Glowing light sources with bloom
- Better light penetration in caves and overhangs

### 🌍 World
- Procedural sky gradient with sunsets
- **Realistic clouds:** grayer where they are thick, wispy and transparent at the edges, with a silver lining against the sun
- Waving grass, flowers and leaves
- Subtle atmospheric haze
- Cinematic ACES tone mapping

### 🧭 Built-in HUD
- FPS counter and coordinates (top-left)
- Compass at the top of the screen (N, E, S, W) with green dots marking visible players
- Both can be turned off

## ⚡ Performance
Cristalino is built to stay light:
- Short, low-resolution shadow map with smart sampling (fewer samples far away, none in caves)
- Reflections are only traced where they matter; rough or distant surfaces use the sky
- Bloom reuses image mipmaps instead of extra passes

**Profiles:** Minimum · Performance · Balanced (recommended) · Quality

## 📋 Requirements
- Minecraft Java Edition **26.2+**
- **Iris** (1.11.x or newer) + **Sodium**
- Fabric or NeoForge

## 📦 Installation
1. Install Iris and Sodium for your Minecraft version.
2. Put `Cristalino.zip` (do not unzip) into `.minecraft/shaderpacks/`.
3. In game: **Options → Video Settings → Shader Packs → Cristalino**.
4. Choose a profile and tweak settings to your liking.

## ⚠️ Known Limitations
- Reflections are screen-space: only what is visible on screen can be reflected; everything else falls back to the sky.
- Translucent gems and ice are still solid blocks to the game, so placing them inside a wall can let you see through it (x-ray effect). Disable **Materials → Translucent gems & ice** if you prefer them solid with simulated depth.
- Green player dots on the compass only show players currently rendered on screen.
- The compass may overlap boss bars (Wither, Ender Dragon).
