Light big room

I have a very big open office room and I am trying to light it. I am trying to put about 50-60 spot lights on the room with big angle. When I am getting to 15 lights the game starts to be little laggy so if I will reach to 60 the game will stuck. I understands that placing alot of lights on the same room is not the right way to light this big room. I have tried to put less lights with big intensify but the reasolt is not very good. Too shiny places and too dark places. How can I light this big room?

I have a couple ideas.

  1. Maybe you should uncheck cast shadows…If you can get away with that it’ll REALLY help.
  2. Maybe consider a directional light. You can also have IT not cast shadows.
  3. There are a bunch of settings in the details panel that may assist. Keep attenuation radius at a minimum if possible…and strength obviously…and no remember to build your lighting!!

Also. The type of light it is? Static, dynamic, can really affect performance.
