Create ONE photorealistic game diffuse wall texture atlas in EXACT 2 columns × 2 rows, equal boundaries at 50%. Each tile is a clean frontal architectural elevation of ONLY THE RECTANGULAR MAIN LOWER BUILDING WALL from ground-floor doorway threshold to roof cornice. DO NOT INCLUDE domes, bell towers, roofs above cornice, sky, triangular roof silhouettes, trains, rails, platform objects, fences, trees, people, cars, poles or wires. These removed elements are modelled separately in 3D. Neutral daylight, clean straight geometry, photographic material detail, wall edge-to-edge in every tile. Reference images are architectural references and depict four buildings in Oryol, Russia. TOP LEFT: Oryol railway station lower main passenger hall, ochre/yellow plaster and ornate cream surrounds, red/orange pilasters, tall arched windows and original entrance doors with cream trim, symmetric historical railway station facade, small ВОКЗАЛ ОРЁЛ lettering; no train or railway tracks. TOP RIGHT: Epiphany/Bogoyavlensky cathedral lower rectangular white stucco wall from its reference, arched door at centre and narrow framed rectangular/arched windows on either side, white baroque cornice and delicate plaster relief; no black dome or bell tower in tile. BOTTOM LEFT: Mikhailo-Arkhangelsky cathedral lower two-storey pale yellow cream wall from its reference, green horizontal cornice and neat white classical pilasters, rectangular white-framed windows, centrally aligned doorway; no tower/dome. BOTTOM RIGHT: Kazan church of Presentation convent in Oryol lower white ornate wall from supplied reference, three tall arched windows with ornamental white stucco frames and white pilasters, carved cornice; no blue roof/dome. Texture atlas, NOT street photo collage. Every rectangle fully filled with that building's main wall; no surrounding backgrounds or empty margins. Preserve photographed wall details, reconstruct occluded portions naturally.
