Chrome Arcology Transit Terrain

Procedural terrain generator for the Chrome Arcology Transit kit: a 64m chunk of the kit's own ground, with knobs for its landforms, detail and palette. Set edges to tile and it joins any other FreeMater kit's terrain edge to edge with no seam.

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
