I think “realtime GI solutions” is not main subject. We have to talk about new renderer. I totally agree with suggestions. Lightmass calculation and quality, swarm distribution methods look old fashioned and time consuming. I tested network rendering for swarm and it is really useless. Cores does not work together. You can not use your cores efficiently . As said before that one core has a job and another cores wait in vain. Unreal team must write new renderer in short term, maybe in UE5.
