@DrDoom9. I was about to add the following piece of Ascii art that illustrates the point
If we have a scene comprising a row of 9 objects and a camera looking at the centre of that row this looks like
1.2.3.4.5.6.7.8.9 Scene
........V........ Camera
where I have used a V for the camera because it looks like a field of view
If we increase the camera position (and its target) by +4 units this becomes
1.2.3.4.5.6.7.8.9 Scene
............V.... Camera
(If we did not increase the camera's target at the same time as increasing its position then the camera would end up oposite scene object 7 but pointing somewhat backwards towards object 5. How big that camera rotation would be depends on just where the target was placed, if it was exactly at item 5 then the camera would rotate to exactly ponit at it, if it was a long way behind item 5 then the rotation would be much smaller)
If instead we increase the position of everything else by +4, which is what happens if we nest everything in the scene other than the camera into a single node and change its position by 4. we get
....1.2.3.4.5.6.7.8.9 Scene
........V........ Camera
(If we move the scene there is no need to compensate using the target position)
I have never tried it, but I suppose you could nest everything including the camera into a node and move it by 4 units in which case you would get
....1.2.3.4.5.6.7.8.9 Scene
............V........ Camera
but that would not be very useful.
