Sleeper Stack

Stack of spare timber sleepers by the line: 2.6 m creosoted sleepers laid crosswise in alternate layers on two bearers, slightly uneven ends; a layers knob of 1 to 6 sets the stack height. Wear greys the sleepers toward silver and splits a few ends.

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
