concrete brick 3d model

Create a realistic solid cement brick with perfectly sharp 90° edges, flat faces, and accurate rectangular proportions. Use a light grey cast-concrete material with fine stone aggregate texture and subtle manufacturing imperfections only. In the exact center of one large face, create a recessed rectangular panel containing the bold uppercase text "LNE". The letters must be deeply embossed as real geometry, perfectly centered, evenly spaced, crisp, and sharp—not a texture or decal. Maintain clean hard-surface topology, watertight manifold mesh, and production-quality geometry. Avoid rounded corners, melted surfaces, warped faces, distorted text, noisy mesh, cracks, bevels, extra objects, background, or lighting. Single clean object, optimized for Blender, CAD, and PBR rendering.
