Lighting System Actor

Asset location: CloudsLighting/Blueprints/BP_CloudsLightingSystem.  

When placed into the world Lighting System Actor collects all the data about volumetric light sources in the same world. The data is encoded into the Render Target, that Lighting System Actor owns.

The position of Lighting System Actor doesn't matter.


You need to place exactly one Lighting System Actor into the world to get lights work.
