Semi Tractor

1950s long-nose conventional semi tractor, 6.5 m long, 2.5 m wide, 3.2 m to the cab roof: a long hood with a tall chrome grille and round headlamps, a rounded cab with a split windscreen, twin vertical chrome exhaust stacks.

风格：low-poly, flat-shaded vertex colors, no textures, 2 materials: the shared opaque one plus a distinct surface (glass, water or chrome), which stays its own mesh through mergeAssets rather than merging into the rest; shares palette and scale with its kit
