@Jacksy Welcome to the community! A little bit more information would help me answer your question. What type of data are you trying to upload? What is your use case - are you trying to upload terrain to cover large parts of the ocean or smaller bodies of water such as rivers or lakes? In the meantime, here is a guide covering CesiumJS support for visualizing terrain and water effects. > **[Visualizing 3D Terrain](https://cesium.com/learn/cesiumjs-learn/cesiumjs-terrain/)** > > This tutorial demonstrates how to visualize 3D terrain, using Cesium World Terrain as an example. I suspect that this guide will have a lot of the information that you are looking for. I also found [this community forum post](https://community.cesium.com/t/rendering-the-water-using-ue4/13054) that discusses water masks in Cesium for Unreal. -Sam --- _[View the full topic](https://community.cesium.com/t/by-now-is-there-cesium-terrain-builder-tools-or-scripts-to-generate-cesium-terrain-tiles-with-water-mask-extension/8690)._
