To zoom out I use manual zoom. Right mouse click and it's one of the options. Then just drag your mouse down. You can zoom out pretty far that way. The advantage of large objects far away as opposed to small ones close up in order to simulate distance is that with the large and far you have a more accurate to reality representation and Vue puts in all it's atmospheric haze and fog like it would have in nature.

Truth has no value without backing by unfounded belief.
