Sanatorium Concrete Albedo

Generated from: Seamless tileable photorealistic PBR albedo texture, 2048x2048, of weathered poured concrete on the exterior of an abandoned Soviet-era brutalist psychiatric hospital. Cold desaturated grey concrete, rough and porous, with patches of green-brown biological discolouration and damp mould, widespread orange-brown rust bloom bleeding down from an unseen metal fixing, long vertical dark grime and water streaks running down the surface, hairline cracks, chipped and spalled corners, salt efflorescence, dark damp patches. Flat orthographic front elevation filling the entire frame edge to edge, even overcast diffuse ambient light, no baked shadows, no directional highlights, no perspective distortion, no windows, no objects, no text, no watermark. Edges match exactly on all four sides for seamless tiling. Coverage represents about 4 metres square. Very detailed, grimy, bleak, mid-dark value, not clean, not uniform, not bright.
