add facade lighting based on the blue arrows shown in the image the arrows are only directional guides and must not be rendered modified or treated as objects the lighting should originate from the ground floor level only exactly where the arrow bases are located the light should follow the direction indicated by the arrows projecting onto the facade surfaces as architectural uplighting or wall washing the blue arrows must not be visible in the final render and must not influence the scene visually in any way use warm white light approximately 2700k 3000k with soft realistic falloff and natural diffusion on the facade do not add lighting to upper floors or any areas outside the marked ground floor zones do not modify windows cornice lighting or any existing lighting elements keep the camera angle composition materials textures and geometry unchanged the result should be physically realistic architectural lighting with correct directionality and no graphic or ui like elements visible
