Waterways and Oceans

Cesium for Unreal
1

Hello there! I am working on a digital twin for a Swedish government and they are trying to simulate different waterways and locks.

I am wondering if there is a way to import waterway data and create procedural waterways, lakes and oceans in Unreal on top of this data.

I can handle procedural water within the UE, but I am trying to find a way to import this layer into the Cesium. Also, I wonder if it’s able to have precise depth within this data so I don’t need to create this landscaping myself (it’s over 70 kilometers of waterways).

If there is a similar topic, just point it to me, so we don’t spam the forum.

I really appreciate any help you can provide.

The details depend a bit on the format of your waterway data, but it’s probably possible. For example, if you have a GeoTIFF or similar with waterway height (-depth) values and either “void values” or actual terrain heights outside of the waterways, you could import that into Cesium ion for layering on top of Cesium World Terrain. Then you would simply have to point a Cesium3DTileset actor at the ion-created asset in Cesium for Unreal. The waterways would look like trenches to start, but then you could use normal Unreal tools to create a water surface mesh to go over the top of it.
