About Dynamic Water Physics 2 – Unity Editor Tool & Plugin

Unity Water Physics Simulation and Buoyancy Tool

Dynamic Water Physics 2 is a physical simulation framework that uses mesh data to simulate buoyancy and hydrodynamics across maritime environments in Unity. Designed to handle objects of any shape or scale, the system calculates physical interactions for surface vessels, floating debris, and fully submerged vehicles without applying artificial transform translations.

Hydrodynamic Forces and Mesh Simplification

The core simulation engine applies forces directly to standard Unity Rigidbodies, ensuring all water/object interactions integrate naturally with surrounding physics systems. High-polygon visual models can be used without reducing frame rates because the system incorporates an integrated algorithm that generates a simplified simulation mesh specifically for hydrodynamic calculations. Setup can be performed manually or configured quickly using an automated one-click wizard.

The tool includes dedicated vehicle control scripts, featuring a modular ship controller supporting inboard and outboard engines with audio, multiple rudders, and bow and stern thrusters. An additional script provides specialized handling for submarines and underwater navigation. The asset also includes networking compatibility for multiplayer titles via Mirror and PUN2, alongside automated water effects for flat water setups.

Water Asset Integrations

The package functions as a physics engine rather than a visual water renderer. It natively reads surface and wave data from popular environment assets, including Crest, Unity HDRP Water, Stylized Water 2 & 3, KWS Water System, R.A.M, Lux Water, and general flat water shaders. Rendering pipelines supported include the Universal Render Pipeline and the High Definition Render Pipeline.

Use Cases

• Suitable for naval combat titles and boat simulators requiring realistic hull hydrodynamic forces and multi-engine steering.
• Can support underwater exploration games utilizing the dedicated submarine script for ballast and dive physics.
• Useful for maritime survival games needing performant floating debris and cargo buoyancy across multiplayer sessions.
