I recently had an idea I wanted to try for faking dynamic global illumination in Unreal Engine 4 using nothing but the tools UE4 provides. Since there are no extra light sources used to achieve this effect performance is rather good.

I built this from the ground up using mostly blueprints, it is not using any of the existing GI systems built into UE4 like DFGI, or LPV, it is a custom setup. Outside of the spotlight illuminating the scene there are no extra light actors/point lights etc added to the scene to achieve these results. This is not in any way meant to replace any of the built in systems in UE4, more than anything it was just a fun experiment I wanted to try out :)

If I get enough interest I'll try and get more videos up showing this system in a little more depth, and in a more regular map environment.

Song used in this video was "There's No Light At The End" - bought from and made by TyberCore
