Warning: Tile has a bounding volume that does not include all of its content, so culling and raster overlays may be incorrect

Hi, When loading a custom terrain (https://geodan.github.io/terrain/samples/maastricht/tiles/layer.json at 50.818219, 5.702376, 250) in Cesium for Unity3D (v1.4.0) the terrain is visualized, but there is a warning:

[2023-07-18 13:01:14.812] [warning] [TilesetContentManager.cpp:416] Tile has a bounding volume that does not include all of its content, so culling and raster overlays may be incorrect: https://geodan.github.io/terrain/samples/maastricht/tiles/0/0/0.terrain?v=1.1.0&extensions=octvertexnormals upsampled L6-X62-Y40

There are warnings for terrain tiles 0/0/0, 0/1/0, 2/4/3. In CesiumJS there are no such warnings for this terrain (https://geodan.github.io/terrain/samples/maastricht/).

Questions: What’s causing this warning and what can be done about it?

Hi @bertt,

I think the error message is erroneous, probably triggered by the Mercator quantized-mesh terrain. I wrote an issue for it:

Let me know if you see any actual issues with raster overlays. I’m not sure offhand if you will or not.
