DEM Earth has the ability to automatically align a c4d sky object, or a sun expression tag to the DEM Earth.
This can be used to easily line up your c4d scene lighting, with the lighting from a sat image.
In the World Info / Driver Tab, there is an object link field for a Sun Object.
Create a Sky Object.
Drag and drop the sky object into the Sun Object Link Field.
Best is to disable shadows in the sky object.
Then, simply adjust the month and time of day, until the sun is aligned parallel to your shadow lines.
using this link method, it is very easy to align your lighting to match your imagery.
The advantage of the driver link is that you don't have to set the coordinates yourself. And when you pan around, the sun is fed the new coordinates.
