Add/design light in scene
19:00 to 30:12

2.Drag light (e.g. "Rect Light", Directional Light) on windows in scene:
Detail: Tick "Cast Ray Tracing Shadows", Set "Movable" at Mobility
3.Drag "Post Process Volume" in scene: for Clean Lighting State and control Ray Tracing performance
Detail: Bloom, Lens Flares, Image Effect : intensity 0, Exposure (min & max EV: 1), Rendering Features (Ray Tracing Ambient Occlusion, Ray Tracing Reflections)
Tick "Infinite Extent (Unbound)", so the effect applies whole set, not just the square area
At "Screen Space Reflection"->Misc , set screen percentage (for better anti-alising if higher %, but heavier on graphic card). So if it's 4k or above image, don't set higher than 150%.
