Why Eevee doesn't illuminate more than 128 lights in a scene in real-time? I don't know if it is a bug or a limitation of Eevee, but the bigger scenes actually needs more than 128 lights. Also, Eevee doesn't bake more than 64 irradiance volumes. If it is not a bug, is there a culling option how to deactivate those lights and light probes that are behind the cameras, behind any object without a visual of them on the camera? 
Thanks.
This is a current limitation:

For your second question look here: Automatically hide everything out of camera view?
