sun postion/direction

My sun is at the horizon between sky image 1 and sky image 2. Can someone tell me what the settings would be for the sun? I can't figure it out.

In addition to the tutorials that Matthew referred to above, Richard O'Brien and I submitted a "Utilities for Mappers" resource that includes a sun vector calculator:

Here is a screen grab showing the normalized vector based on azimuth and altitude:

Being normalized, it's ready to put directly into the editor.

What I found is reliable, but crazy. It seems to work roughly like this:
if (x > abs(y)) { draw_correct_shadows(); } else { screw_up(); }
in other words: as long as x is greater than the absolute value of y, everything is fine. e.g. x=0.4 works with both y=0.3 and y=-0.3
However, x=0.3 works with neither y=0.4 nor y=-0.4
I'm not familiar with the Torque code very much (except for some primitive scripting), but maybe this helps someone to find the problem.

I've hit the same problem, and done some experiments. Namely, I've played with the x and y values and tried to spot a pattern.What I found is reliable, but crazy. It seems to work roughly like this:

tnx Desmond, I'll check that out. I dunno the exact altitude... but now I think I found a way to kow that... I should do some more testing with this.. heheh
