Why we need this tool?

For an LED project, the gaffer team set up a sunlight matrix by arranging multiple light panels around the center of the stage to simulate directional sunlight.

To integrate this setup with Unreal Engine, I developed a tool that links a directional light in the Unreal level with their physical light setup. This ensures that the physical lights remain synchronized with the UE environment displayed on the wall.

The video shows if the directional light moved, it will update all the lighting with smoothness value, and send it to the light through DMX sACN protocal.
