What are the tricks to get a physical sun (real-world location) in FR2 to agree with C4D's SKY and its solar position?
I'm rendering interiors for a building that is curved and mostly glass, so having fairly accurate sun shadows is important to my client.
I'm starting with a scene rotated from true north. I rotated the C4D SKY object by the offset and it looks about right for the location (New York City area).
Now I'm trying to get FR2 to match the results in AR. I added a NULL at world origin. and have rotated it also, dropped it into the 'compass' slot in FR2. But my FR2 sun shadows are way off from ARs. I put in the long./lat. and remembered that negative = west. Still off.
What am I doing wrong here?
