Tutorial: Connect Sun Lamp and Sky Texture (Blender 2.70)
If you'd like to skip the intro and explanation go to 4:30
All information is in the description!
This video explains how to connect the direction in which a sun lamp is pointing and the direction in which the sun in a sky texture is pointing in order to match them up using python.
I know this isn't the only way to do this, but it's the method that I found most intuitive and easy to understand. I hope you find it useful!
Update! : I improved the code thanks to TheRealWinsletFan, I posted the improved version here: / ive_got_another_tutorial_for_you_guys_this...
