I would like to have a direct control over the time of day without having to rotate the DIRECTIONAL LIGHT.
I believe there may be a blueprint for this but I guess it should come with a tool or a special light where you can precicely set the time of day or night and the timezone so that you get an accurate simulation of shadows cast in a specific place in the world.
I know that is a tool used mostly in Architectural Visualization but it could prove useful also to Game developers as well.
It is available in 3ds max and Sketchup and other packages. It’s simply called Daylight system.
If this issue has been raised or solved, or maybe there is a tool like that already I look forward to someone directing me to it.
