Hi, When loading a custom terrain ([https://geodan.github.io/terrain/samples/maastricht/tiles/layer.json](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:

```auto

```

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/](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.
