Corridor Section

Pressurized corridor section, exactly 4m long, octagonal hull cross-section 3m wide and 3m tall, off-white panels with a cyan light strip; both open ends terminate in the kit standard collar cross-section.

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
