I would like to add a moving water effect in a 3D world. How do I achieve this? I want my Cesium Map to look like this. I could recreate all arrows and tags but adding a rippling water effect I could not achieve. This is my first post and I hope to contribute more to create digital twins! ![image](https://global.discourse-cdn.com/cesium/original/3X/7/d/7d6d0465771a37681375269dc810ab1da3215bbc.jpeg) ---

Hi @Robin_Valk, welcome to the community! Cesium for Unreal provides the option to toggle a water mask on the data you’re loading. However, the data _must_ include this water mask data itself. Cesium World Terrain comes with this water mask, so you can enable it using the **Enable Water Mask** setting on the **Cesium3DTileset**. ![image](https://global.discourse-cdn.com/cesium/original/3X/5/0/5034f89477ffc094de7d4c3650eb01e54b0213e0.jpeg) Otherwise, if you’re using some other data, you may need to emulate this effect manually in a material. Maybe a naive start would be to apply the moving water effect to any areas that are blue. Let us know how it goes!
