The Unreal water system is supported through the use of a “Water Mask,” which tells Unreal which spots in the tileset have water and which do not. Our FAQ [gives instructions on enabling this for Cesium World Terrain](https://cesium.com/learn/unreal/unreal-faq/#what-is-the-water-mask-how-do-i-enable-the-water-mask-on-cesium-world-terrain). For a tileset of your own, or a tileset that doesn’t have a water mask, you can try creating your own water mask or a material that has the same effect, [as detailed in this post](https://community.cesium.com/t/custom-water-mask/25179). I hope that answers your question!
