Realistic lighting

The lighting stage of 3D modeling is about reproducing the light properties we meet in the real world — realistic lighting. To make it right, 3D designers use the Cornel box.^[1] It's a well-known method developed at Cornell University that 3D artists use to determine how accurately their computers render the lighting. With all the specific properties and specifications, such as the source of light direction and intensity, the colors of walls, objects' textures, and their position in the room, the method compares the outcome image with an actual photograph of the same scene.
