Godot Water Shader Demo 🌊

This project showcases a Gerstner wave ocean shader built in Godot 4.
The shader simulates realistic ocean movement, caustics, foam, and depth-based color blending.

The repository includes:

• A main demo scene with islands, props, and a player.
• A customizable shader with grouped uniforms for waves, depth, foam, and surface details.
• Support for caustics, edge foam, peak highlights, and noise-based surface variation.

Features

• 🌊 Gerstner Waves for natural ocean motion
• 💡 Caustics projection
• 🫧 Foam effects
• 🎨 Depth-based water coloring (shallow vs. deep)
• ⚙️ Customizable shader parameters for fine control

How to Use

1. Clone or download the repository.
2. Open it in Godot 4 (This project was last tested in 4.5).
3. Run the main scene (world.tscn) to explore the short demo.
4. Apply the shader to a plane mesh in your own project.
   • Increase mesh subdivisions for more detailed waves (⚠️ watch performance on large meshes).

Notes

• For large planes (e.g. 500x500), subdivisions above 1000 may impact performance.
• Shader parameters are grouped for easy tweaking inside the inspector.
