Lighting is an important factor in conveying the design intent. When rendering a 3D view of a building model, you can use natural light, artificial light, or both to illuminate the building.
For natural light, you specify the direction of the sunlight, or the location, date, and time of day to achieve a realistic representation of sunlight on the building.
For artificial light, you add lighting fixtures to the building model, organizing them into light groups if desired. Before rendering, you can turn on or off individual lighting fixtures or light groups to achieve the desired effect. The resulting rendered image shows the effects of lighting on the design.
