Ant Nest Entrance Mound

Ant nest entrance mound, the colony's front door: an 8m-wide, 2m-tall crater of excavated soil crumbs (faceted pellets 0.2-0.5m in loam and clay browns) heaped round a central shaft with exactly the 2.4m Ant Tunnel Run bore, dropping into darkness.

风格：low-poly, flat-shaded vertex colors, no textures, single shared material, so any set of these merges to one draw call; shares palette and scale with its kit
