In some contexts, the position of the Sun in the sky is not an aesthetic choice. Instead, it is a critical design factor.
This is often true in large architectural and construction projects, but it may apply any time you need to produce true-to-life renderings that show realistic patterns of sunlight and shadow.
In these cases, you need to be able to place the Sun in your Unreal Engine Level precisely, according to the same mathematical equations that govern the position of the Sun in the real sky of Earth. These complex equations incorporate a number of settings that include the geographical location of the observer on the globe, the date, and the time of day.
The Sun Position Calculator Plugin solves these mathematical equations for you in the Unreal Engine. You define the latitude, longitude, cardinal points, date, and time of day. Then, the Sun Position Calculator works in tandem with the default sky sphere in the Unreal Engine to place the Sun disk in the sky sphere and to orient the main Directional Light in the Level.
