I’ve noticed that when adding terrain assets to Cesium Ion, they are not rendered correctly in Cesium for Unreal. CesiumJS has no issues correctly displaying the assets but the UE4 plugin has multiple issues.
As an example, I created a new empty UE4 project and added the base Cesium actors to get the globe to render in the scene. If I change the Cesium3DTileset’s Ion Asset ID to the generated asset, it will display with artifacting and holes in the globe.
The elevation geotiff I used was from the sample data here.
This was generated using the Mean Sea Level terrain. Asset ID 618922
This was generated using the Cesium World Terrain. Asset ID 618938
Any ideas on why the rendering is different between Cesium for Unreal and CesiumJS?
