Hi,

I ran Cesium Ion’s `model-tiler` on a `gltf` file, and generated a `tileset.json`. I then hosted the file into the asset server and loaded it into my viewer. (See code below)

```auto
viewer.scene.primitives.add(
  new Cesium.Cesium3DTileset({ 
    url : 'http://localhost:8002/static/tiles/gltf-test/tileset.json',
  })
);

```

The 3d tileset appears on the screen but when I try to zoom out suddenly the model disappears out of no where.

Any clue what would be the issue?

Thanks!

Hi @iramgelb!

Can you please share the account email address which has access to the model tiler?

Best,
