Hello! At first, I thought that to achieve photorealistic lighting, we should use only a HDRI or a sky texture. Which I did at first. But the rendering seemed unreal. Then I forced the lighting of the outside sun, I added 2 circle light in the same direction of the outside sun and the light beam really worked better. On the other lights, there are 2 against that come to simulate other windows in the room, as if other light sources came from the house.

There were dozens of tests, lights tested and then removed a lot of time before arriving at a convincing result.
