Dynamic Water Physics 2

Dynamic Water Physics 2 is a water-object interaction simulator that uses mesh data to simulate both buoyancy and hydrodynamics, making it suitable for objects of any shape or size, moving or stationary.
DWP2 is a complete rewrite from the previous version to make use of new Unity features and get even better performance.


• Fast and easy to setup - either manually or through one-click wizard.

• Simulate any object of any shape or size, as long as it has a mesh.

• Extremely well optimized. ~0.02ms CPU time on average per object in the demo scene, ~1.2ms total for 70 objects. (Wavy water performance depends on 3rd party asset used)

• Utilizes Burst-enabled Unity Jobs to make use of multiple CPU cores.

• WaterObjects are ribidbodies and interact with water only through use of forces. No translation or rotation applied.

• Uses in-built algorithm to generate a simplified simulation mesh meaning that high-poly models can be used without affecting performance.

• Suitable for both desktop and mobile.

• Works with any positive object scale.

• Works under water.

• Water effects work with any flat water and are auto-generated using simulation data.

• Included C# source code, manual and everything seen in the demo.


• Ship controller that can be used together with WaterObjects to make drivable boats and ships.

• Additional script for submarines.

• Multiple engines with sound, both inboard and outboard.

• Bow and stern thrusters.

• Multiple rudders.


• Crest (free)

• Ocean Community Next Gen (free)

• Ceto Ocean (free)

• Lux Water

• SUIMONO Water System


• All flat water assets (AQUAS, Stylized Water Shader, etc.)

DWP2 is not a water renderer / shader.

NOTE: The basic flat water from demo scene does not work with HDRP. Use water from Unity Standard Assets as a replacement if you need to use HDRP.
