World Light Direction Control
Sun (directional) light ray direction can be set using a graphical vector visualization. The confusing numbers to control light direction are gone.
Northern and Southern Hemisphere
The yellow path on the compass give a hint where to drag the sun, for a natural light setting in northern hemisphere. The blue path describes it for the southern hemisphere.
Without holding down any key while dragging the sun, both previews will only reflect the changes in east - west direction, otherwise they operate independently. This way all possible directions of the light ray are still possible, same as it has been in previous versions.
Left Shift Key
Optionally, while holding down the Left Shift Key and dragging the sun, the other perspective moves accordingly. E.g. when holding shift down and dragging the sun to the south on the left compass, the altitude on the right preview will also raise accordingly to northern hemisphere.
Left Control Key
Optionally, while holding down the Left Control Key and dragging the sun to the north, the altitude on the right preview will also stay above ground accordingly to the southern hemisphere.
Left Shift and Left Control Key
Holding down both, the left control and the left shift key, will reset the position of the sun to when the dialog was opened.
