How to use it on your own project (Tutorial Video):YouTube Link

A hyper-realistic, clock-driven solar rotation system designed for projects that demand cinematic lighting transitions, seamless day-night cycles, and precise sun positioning based on real-world time logic.

Features:

  • 24-Hour Accurate Sun Positioning:Calculates the sun's Pitch (altitude) and Yaw (direction) based on real-world clock inputs: hour, minute, and second. No animations, no curves — just pure math.

  • Sinusoidal Movement for Smooth Transitions:Sun height is controlled using a sin() curve, mimicking the natural arc of the sun — ensuring ultra-smooth lighting changes from sunrise to sunset.

  • Performance-Friendly:Lightweight math-based system. Tick-compatible or timed updating — runs efficiently even in complex scenes.

  • Drag the blueprint into your level, link it to your directional light, and let it simulate a full dynamic sky.
