**1. A concise explanation of the problem you’re experiencing.**

When from afar, buildings start to load but not all of them. Some neighbouring buildings only load when i zoom in very close to the ground.

This happens within the same tilesets.

**2. A minimal code example. If you’ve found a bug, this helps us reproduce and repair it.**

```auto
var building = viewer.scene.primitives.add(new Cesium.Cesium3DTileset({
// url : '/map/data/building/Building',
     url : '/map/data/building/Building',
       maximumScreenSpaceError: 8,
       shadows: Cesium.ShadowMode.CAST_ONLY
   }));

```

Tried changing maximumScreenSpaceError parameter but no success.

The other i read is changing geometric error values. Tried a few changes but stop cause i’m not sure how it works.

**The Cesium version you’re using, your operating system and browser.**

1.38

Hello,

Could you send over the tileset? That would help with verifying if this is a problem with the tileset or Cesium.
