@Kevin_Ring In fact, this problem also exists on UE5.6 + Cesium for Unreal 2.18. There were no issues when using “From Cesium Ion” and “From Ellipsoid”. I think the problem might be with the elevation file ”Layer.json”. This is the terrain I assembled using CesiumLab. When approaching the North and South Poles, white patches will appear.
Hi @Unreal_Miracle,
Yes, it’s possible that it is a problem with the tileset itself. quantized-mesh-1.0 terrain includes minimum and maximum heights. If those are wrong, you might see an error like that. In fact, that error message should generally be interpreted as a data problem, rather than a problem with Cesium for Unreal.
However, it’s also possible that you’re running into this issue, which we believe to be a bug on our end:
If so, we’d welcome a fix for this from the community, but we’re unlikely to fix it ourselves in the near future. It only shows up in tilesets generated by third-party tools, and only when using an older format, quantized-mesh, that we are moving away from (we prefer to use 3D Tiles).
