add facade lighting based on the blue arrows shown in the image the arrows indicate both the placement of the light sources and the direction of the light beam all lighting should originate only from the ground floor level within the ground floor zone where the blue arrows are placed the light should be directed according to the arrows casting illumination upward or along the facade as indicated the effect should resemble architectural facade lighting e g linear uplighting or wall washing highlighting the building surface in a subtle and realistic way use warm white light approximately 2700k 3000k ensure smooth light falloff and natural gradients on the facade do not add lighting on upper floors or in any other locations outside the marked arrows do not modify windows cornice lighting or any existing lighting elements keep the camera angle composition materials textures and geometry unchanged the final result should look realistic with physically plausible light direction soft shadows and no overexposure
