///  - `replicate` (bool)
///
///    If false, this ID will not actually copy the object. It'll be skipped.
///
///  - `scale` (3D point)
///
///    Stretches the object, multiplying its width in the given dimension by the point's component in
///    that direction.      
///
///  - `rotation` (object, with the following properties)
