Hi Jon, for the lens flares I used particles. Three layers of sprite particles. One for the bright center, and two for the outer glows. The material is very basic, it just uses pixel depth so it fades out with distance from the camera. The material property " Disable Depth Test " is unabled. This way geometry does not overlap it, the only issue with this is that the lens flare also is visible behind walls. Therefore at this moment the setup is purely cinematic.
Screens are attached
