do not modify the original model geometry proportions layout structure or placement of any elements keep the exact same architecture forms and design do not alter or redesign any objects in the scene only improve the materials textures and surface details to achieve a significantly more realistic result enhance material accuracy using physically correct textures proper roughness values reflections bump normal maps and subtle surface imperfections maintain the original material intent while improving realism the scene is illuminated by ceiling lighting the lighting should feel natural and believable with realistic light intensity soft shadows accurate reflections and balanced exposure improve global illumination and realistic light interaction with all materials focus on high end photorealism through refined material definition realistic reflections subtle imperfections and natural color grading without changing the model geometry layout or design in any way colour balans is neutral
