Dynamic Water Physics 2 | Physics | Unity Assets

Dynamic Water Physics 2 is a water physics simulation tool that utilizes mesh data to simulate buoyancy and hydrodynamics both above and below the water surface. Suitable for any mesh shape and size.

Render pipeline compatibility

The Built-in Render Pipeline is Unity’s default render pipeline. It is a general-purpose render pipeline with limited customization options. The Universal Render Pipeline (URP) is a Scriptable Render Pipeline that is quick and easy to customize, allowing you to create optimized graphics across a wide range of platforms. The High Definition Render Pipeline (HDRP) is a Scriptable Render Pipeline that lets you create cutting-edge, high-fidelity graphics on high-end platforms.

Additional compatibility information

This asset is a physics asset and aims to be render pipeline independent. However, the included demo flat water shader reflections do not work with URP or HDRP meaning that a 3rd party water shader will have to be used in that case. DWP2 works with all flat water assets/shaders and multiple wavy-water shaders.

Description

Dynamic Water Physics 2 is a water/object interaction simulator that utilizes mesh data to simulate both buoyancy and hydrodynamics, making it suitable for objects of any shape or size, whether moving or stationary, and whether above or below the water.
 

This asset is part of NWH Physics World, a collection of interoperable vehicle simulation assets.
 

MAIN FEATURES 

• Fast and easy to set up - either manually or through the 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)

• Multiplayer support (Mirror and PUN2).

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

• Uses an 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 underwater.

• 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

• 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.

SUPPORTED WATER ASSETS

• Crest

• KWS Water System

• Stylized Water 2

• R.A.M

• Ceto Ocean

• Lux Water

• SUIMONO Water System

• Ocean Community Next Gen

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

DEMOS

Demos are available for Windows, MacOS, and Android.

NOTE: DWP2 is not a water renderer / shader.
 

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