UE5
You can use Water Body Actors to define the location and shape of the water surface and their transitions in the level. Water bodies are made up of water mesh tiles that are managed by the Water Mesh Actor. This actor sets the quality and properties of all water bodies. You can set the water mesh actor up to cover the area where you want water bodies rendered. When you do so, Unreal Engine automatically generates the needed mesh. Rendering all the water bodies as a single water tile mesh allows for smooth and seamless transitions between them.
Water Bodies also determine wave movement and shading of the water surface, as well as the underwater post-processing. Each water body contains information about its depth and flow. You can query these for gameplay usage. For example, you can create physics interactions with the water's surface.
-Types of Water Bodies
There are several types of Water Body Actors to choose from.
Water Bodies for Oceans, Lakes, and Rivers. These are all defined using splines that store data about their type.
A Custom type. This also has a spline for querying data, but you define the shape with a Static Mesh.
An Island. This is used to raise landscape terrain within a defined spline area.
An Exclusion Volume. You can use this to create underwater zones where gameplay can act as if it was not under water.
To add a Water Body Actor to your Level:
Go to the Place Actors panel, select the Water Body Actor, and drag and drop it into your level
In this video, I'll show you how to add water with the water plugin in Unreal Engine and change its color. It's a simple process, but it can make a huge difference in the overall look and feel of your game.
First, select "Water Body Ocean" if you want to change the color of your water. This technique works with all other water types, such as lakes and rivers.
Next, scroll all the way down to the rendering section and double-click on the water material. Don't worry if you don't see anything at first.
Scroll down to the absorption section and enable it. From there, you can easily change the color of your water. You can also play around with scattering and foam color to make it look even better.
