How to get global lighting during gameplay

I want to have global lighting during gameplay so I can better see my map. I dont want to use lights because that would take too much time to render and move around and place tons of lights etc, is there a way i can just enable global lighting during gameplay?

Maybe placing only one skylight in the map? If you set it to movable you won’t need to render lightmaps and you can mess around with DFAO to add some ambient shadowing to your scene or just disable all the shadows to get only the flat global lighting you may be looking for.

Not sure if this is what you are looking for but in the top left corner of your screen, change the button that says lit, to unlit. Then you will be able to see your map better. Shortcut on keyboards is ALT+3
