use the provided rendering as the base image use the two additional reference images only as material references reference 1 material reference for the paved area in front of the garage reference 2 material reference for the staircase steps important this is strictly a material and realism update only the entire geometry of the scene is fixed and approved do not change anything about the architecture or layout absolute preservation rules keep exactly unchanged camera position perspective framing composition staircase geometry curved widening shape of the staircase number of steps step dimensions stair width stair height terrace geometry ramp geometry all levels and heights retaining walls stair side walls cheeks railings path layout garage forecourt layout house garage bench vegetation furniture all object positions do not redesign anything reinterpret anything move anything rotate anything straighten anything adjust proportions change heights change alignments change transitions change silhouettes only change the materials and increase the realism material instructions 1 staircase steps use reference 2 as the direct material reference for the staircase steps apply this material only to the visible step surfaces the steps should read as solid stone block steps with the exact material character of the reference match the color texture reflectivity surface grain and natural stone appearance do not change the geometry of the steps in any way 2 area in front of the garage use reference 1 as the direct material reference for the paved area in front of the garage match the large format slab appearance warm light tone joints and realistic stone texture of the reference apply this only to the garage forecourt surface do not change the layout or dimensions of the area 3 garden path keep the garden path as a sand fine gravel path with paving stone edging only improve the realism of the material do not change the shape width alignment or border 4 stair side walls cheeks keep the stair cheeks as simple white plastered surfaces no stone caps only improve the realism of the plaster texture do not change their shape height thickness or position 5 hyperrealism make all visible materials more realistic so the final image looks like a real photograph increase realism for stone materials plaster metal railings roof tiles windows and reflections vegetation lawn shadows contact shadows subtle imperfections overall light behavior final goal the final image must be geometrically identical to the input rendering it must look like the exact same scene with the exact same architecture and dimensions but with upgraded materials and much stronger photorealism only material and realism may change nothing else
