Modern 2D Water : 2/2.5D simulated URP water

🌊 Bring beautiful, interactive water to your Unity game!

Modern 2D Water is an advanced, customizable water system for top-down games, platformers, pixel art, and 2.5D environments.

Create topdown and platformer water, from basic shapes to lakes, rivers, oceans, or small ponds with real-time wave simulation, reflections, refraction, foam, and dynamic interactions. Water can react to moving objects, generate waves when something falls into it, and reflect the surrounding environment.

You can customize almost everything directly in the Unity Inspector, without having to write your own shaders or simulation code.

🌊 Water Simulation

Make your water react naturally to what's happening in your game!

• Fast, real-time wave simulation
• Rigidbody interactions with water
• Automatic surface waves
• Rain ripples and wave generation
• Special surface wave simulation for platformers
• Water interactions with 3D objects
• Infinite scrolling water
• Limitless wave simulation mode
• Adjustable wave behavior and simulation settings

🪞 Reflections & Obstructions

Water can reflect its surroundings and react to obstacles, giving your scenes much more depth.

• Reflections for top-down and platformer games
• Raymarched reflections for tilemaps and surfaces
• Reflection support for static 3D meshes
• Raymarched water obstructions
• Obstruction support for static 3D meshes
• Foam generation around objects and shorelines
• Distance-based color gradients around obstructions
• Adjustable reflection fading
• Distortion and refraction effects
• Gaussian, Box, and Bokeh blur

🎨 Appearance & Effects

Whether you're making a cozy pixel-art game or a detailed fantasy environment, you can adjust the water to fit your art style.

• Customizable water color gradients
• Surface foam and edge foam
• Animated sun streaks and light strips
• Custom water textures
• Pixel-art rendering support
• Wet surface overlay effects
• Custom tiling and perspective settings
• Rain particle effects
• Optional URP 2D Light interaction

Most effects can be configured independently, so you have plenty of control over the final look.

🛠️ Easy Setup & Integration

Modern 2D Water is designed to work with different types of Unity projects, including existing scenes.

• Top-down, platformer, and perspective camera support
• Unity Pixel Perfect Camera compatibility
• Basic Cinemachine 2D camera support
• Sprite sheets and Sprite Atlas support
• Sprite Skin support on compatible Unity versions before Unity 6
• Create water by drawing on a Tilemap
• Spline Sprite support
• Prefab workflow support
• Multi-scene and bootstrap scene support
• Configurable URP 2D Lights integration

⚡ Performance & Optimization

The system includes 3 water shader variants, allowing you to choose the features you need and avoid unnecessary rendering costs.

You can also adjust simulation and reflection texture resolutions, disable effects you don't need, and fine-tune the water for your target hardware.

The system supports both very small and large water bodies, making it useful for everything from small decorative ponds to large environments.
