I process the local lunar terrain and load it onto the ball in cesiumjs, the terrain loads successfully, but the result will look like a photo, how can I fix it?

Hi there,

Is it possible to provide a code example which replicates this behavior?

Thanks,  
Gabby

Maybe it’s a bit of a problem to define the sphere, I removed part of the code to define the moon, and the problem was solved, but I don’t know why this is happening?

Thanks!

The terrain APIs were [updated in 1.107](https://github.com/CesiumGS/cesium/blob/main/CHANGES.md#1107---2023-07-03). It should now be using:

```auto
const terrainProvider = await Cesium.CesiumTerrainProvider.fromUrl(url, options);

```
