soil berm block 3d model

Realistic outdoor shooting range earth berm (bullet trap), modular and tileable 3D asset. Main backstop berm made of compacted soil and sand, natural irregular surface with small erosion details, no artificial elements. Height approximately 5 meters from ground level, with a crown width of 1.5–2 meters. Slopes follow realistic angle of repose for soil (around 30–40 degrees), ensuring natural stability. The model must be built to real-world scale (meters), optimized for accurate proportions used in shooting range design. Include subtle terrain variation but avoid extreme noise that would break tiling. Tileable design: left and right edges must seamlessly align so multiple berm segments can be placed side-by-side without visible seams. Top surface and slope continuity must match when duplicated. Ground integration: base should smoothly blend into flat terrain, no hard edges. Include slightly compacted soil at the base. Texture requirements: High-resolution PBR textures (albedo, normal, roughness, displace
