UE4 Geographically Correct Sun System

This is a set of components featuring a custom blueprint actor component that links to a default sun and sky system and drives the sun geographically correct in terms of angle and movement. (UE 4.10) It also includes a UMG interface for real time control of the sun system. 

The input points for the determining the sun azimuth and elevation are: latitude, longitude, hour, daylight saving, time difference(UTC) and complete date.

The blueprint is two part: construction and event graph. When playing the level the sun will be positioned and move based on the parameters you set up prior to launching the game (including speed). You can further control these during playtime using the UMG component which is triggered by the 'O' key by default.

Extra features include the option of turning off the sun when it falls bellow the horizon. There's also the option of overwriting the pitch and yaw attributes of the sun for manual positioning.

The position resulted is highly accurate having tested it against results from Revit and also online calculators such as this one:

Everything is cleanly setup with tool-tips for just about all variables and also an accompanying PDF file describing the inner working of the blueprint including the equations used in determining the sun's position.
