If you move the camera away from the object, it will be clipped in the far distance by the `maxZ` property:

> **[Camera | Babylon.js Documentation](https://doc.babylonjs.com/typedoc/classes/babylon.camera#maxz)**
>
> This is the base class of all the camera used in the application. \[API\]

Also, to see entirely your object, you will have to take the object bounding sphere into account. That means, the max distance from the camera to your object is `camera.maxz - object.bondingSphere.radius` (pseudo code here)
