stone pillar 3d model

A single tall, slender upright stone pillar, 3D render, three-quarter front angle, plain light-grey background. Soft even matte lighting from upper left, no harsh shadows, no reflections. Uniform matte mid-grey stone, NO color, NO texture variation, clay/matcap look showing only form. The pillar is clearly much taller than it is wide, a narrow freestanding stone pier. It is built of MANY SMALL hewn stone blocks in regular courses, like fine masonry, with clear joints between the small blocks. In the MIDDLE height band (not top, not bottom), ONE single small block is missing, leaving a small rectangular cavity with interior depth and soft inner shadow so it reads as a real hollow. The gap is the size of just one of the small blocks, tiny relative to the whole pillar. Single centered object, isolated, no second stone, no people, no text, no border, no scene.
