use the uploaded render as an immutable base image this is a precise localized material editing task not a redesign restyling enhancement or complete regeneration change only exact surface or object and apply new material colour or reference texture exclusively inside its original boundaries keep the entire remaining render 100 visually unchanged preserve the exact original architecture geometry dimensions furniture models object placement camera position camera angle focal length perspective vanishing points composition crop resolution and proportions lock all existing materials keep the light natural oak herringbone parquet exactly unchanged identical colour brightness wood grain plank dimensions pattern direction texture scale joints roughness and reflectivity keep the dark walnut veneer exactly unchanged identical warm brown colour vertical grain texture scale and matte finish keep all warm off white walls and ceilings unchanged keep all beige stone marble and travertine surfaces unchanged keep all furniture fabrics white boucl upholstery curtains rugs black metal smoked glass and decorative objects unchanged preserve the original material mapping uv scale texture orientation and surface imperfections lock the lighting preserve the exact daylight direction artificial lighting led temperature exposure white balance global illumination shadows contact shadows ambient occlusion reflections and contrast do not make the render warmer cooler brighter darker or more saturated the new material must follow the original geometry and perspective perfectly maintain realistic pbr properties correct texture scale subtle surface relief natural roughness and physically accurate interaction with the existing light blend the edited material naturally without affecting neighbouring surfaces absolutely no global changes do not reinterpret regenerate beautify or harmonize the complete image do not alter the floor colour or texture do not change any unselected material no geometry changes no camera changes no furniture changes no added or removed objects no lighting changes no colour grading no sharpening no blur and no redesign the final result must be pixel consistent with the uploaded render everywhere except for the specifically requested material change
