Vue will hold fog and haze at the horizon so sometimes just deleting the ground plane is not much help. If you go into the atmosphere editor fog/haze tab and set the fog and haze at zero then sky tab and set the fog in the sky thickness to zero and max. Altitude at zero you can delete or tilt the ground plane out of the way and not have to move the camera this way your objects maybe easier to center when applied to the scene. Thanks for asking this was a very good question. Regards.
