Hello everyone,  
I have a question about new Lumen technology and lighting optimizations.  
I realized static lights could not be used while Lumen is active.  
So I have to use stationary and movable lights.  
When I tried to light a scene with spotlights, rect lights, and point lights I faced an issue. Stationary light overlaps. If I change stationary lights to moveable, it is so expensive and gives not optimized scene.  
So, what should I do to light especially night scenes optimized, and how?

If you want to use static lighting, just turn off Lumen. It’s an approximation of static lighting anyway.

Actually I was wondering that is there any thing to do achieve enough exposure and optimization while lumen is active. I can activate static light easily yeah 😃

I think you have to choose one road. Lumen, or static lighting. If you want a highly efficient lighting system, Lumen isn’t it. 🙂

( It is efficiently executed, but needs decent hardware ).

Walking through the unreal slackers of discord, it seems to me that unless you are going to make a game only outdoors for xbox x and playstation, or for millionaire pc players, or a game that you will release in 5 or more years, you have to continue using traditional methods.
