stone terrain tile 3d model

Create a detailed 3D board game hex tile representing medieval stone terrain as a GLB asset. Hex geometry: regular hexagonal prism where all six sides are equal length and all interior angles are equal (regular hexagon). Circumradius 1.0 unit, tip-to-tip 2.0 units, flat-to-flat 1.732 units, side length 1.0 unit. Orientation: pointy-top hex layout with vertices toward +Z and −Z and flat edges parallel to the X axis. Origin/pivot: hex center at (0,0,0) in XZ. Y=0 at the bottom face so the tile sits on the ground plane. Height: base thickness ≤0.2 units (recommended 0.12). Terrain elevation low for tabletop readability. Terrain theme: medieval rocky terrain with uneven stone ground, clusters of large rocks and boulders, fractured stone surfaces, gravel patches, and cracks in the rock. Some rocks should be partially embedded in the terrain with slight height variation across the surface. Style: realistic medieval fantasy tabletop terrain like high-quality miniature wargame terrain.
