I understand that with a physical sky simulation that sun position based on time and date is a reasonable model to adopt...
however, am I the only one whom hates it?
This model should be an option not the rule.
a simple heading/ascension should be available too. From the ground plain... 0 degrees being due north, 180 being due south, etc.
from the horizon line, 90 being the zenith and 0 degrees being the horizon.
Anyone who thinks this to be a silly request I dare you to make a scene and then ask the sun to be at the direct zenith. Ok, now how long did it take you? Where in the world, and what time of the year does the sun actually stand at the zenith... ummm... I haven't a clue.
However, by typing in 0,180 I could position the sun exactly there... time taken? .00001 seconds. Or for standard scene lighting a 45 degree by 270 would put the sun exactly right for product shots. Plus it's easily adjusted for quick renders and client request fulfillment.
Also, due to the way the sun travels through the sky it's darn-near impossible to do a series of renders with the sun changing position as if it's rotating around the object.

If we had just one lowly SuperStarDestroyer, all of earth's problems would rapidly become rather trite. I mean, who worries about war in the middle east when a 1.5km death triangle is in orbit.
