Light (sun) object properties: X:0; Y:90-altitude; Z:90-azimuth.
I’ve searched to see if anyone has pointed out this little formula before and I don’t think anyone has. The best I can find mentions add-ons or python things. I’m kind of a noob, so I thought I’d share this very easy way to set up a realistic sun angle.
To find altitude/azimuth for your location/time/date just search this site Sun or Moon Altitude/Azimuth Table
