Quick Stylized Water Shader Physics

Create realistic and visually appealing water with an easy-to-use shader and built-in floating physics. This package combines a customizable water shader with a lightweight buoyancy system, allowing any rigidbody object to float naturally on the water surface with minimal setup.

The water shader includes customizable depth colouring, animated refraction, and dynamic foam effects, making it suitable for a wide range of environments such as oceans, lakes, rivers, ponds, and stylized scenes. Every visual parameter is exposed in the material inspector, allowing developers to quickly achieve their desired water appearance without modifying shader code.

The included Floating Object component automatically detects water using a trigger collider and the Water tag. Once an object enters the water, realistic buoyancy, drag, wave motion, and bobbing effects are applied. The system supports configurable float points, allowing both small and large objects to float naturally while remaining stable on the water surface.

Designed for ease of use and performance, the package is suitable for both beginners and experienced Unity developers, making it ideal for games targeting PC, consoles, and mobile platforms.
