在 Unreal Engine 中逐街打造的曼哈顿,从航拍到红砖立面

GPT-6 Astra 在 Unreal Engine 里逐条街道搭建曼哈顿,视频从中央公园一路拍到消防梯和天际线。

Claude Code + Three.js(仅代码)Wandy 2
真实模型 · 360°两者都基于同一张照片:左边是 Claude Code(Opus 5.5)用 Three.js 代码建模的一次未经修改的运行结果;右边是 Wandy 2。

创建精细的 3D 模型

单靠代码只能做出简单的形状。Wandy 2 能用一张照片生成带纹理的 3D 模型,直接用在同一个场景里。

作者没有公开提示词,因此我们写下了复现这个作品的方法。

Build a detailed Manhattan open-world scene in Unreal Engine and record a short camera sequence through it. Start with a high aerial view of the island: the rivers, the long green rectangle of the park, dense blocks and a skyline of towers. Then work street by street at ground level: red brick tenement buildings with fire escapes, arched windows and cornices, a one-way street sign, a glowing neon shop sign, parked cars and a red sports car driving along the avenue. Use natural daylight with long soft shadows, realistic materials and believable street furniture. Keep the grid layout and landmarks recognisable. Deliver the Unreal project plus a roughly thirty-second video that cuts between the aerial view, signage close-ups, facade pans, the car chase shot and a final skyline pass over the water. Done means every street you show is dressed consistently, with no empty or placeholder blocks in frame.

如何使用这条提示词

  1. 在连接 Unreal Engine 项目的智能体会话中,把 build brief 交给 GPT-6 Astra。

  2. 更换城市、街区、时间段或车辆,并列出需要还原的地标。

  3. 让模型逐街制作,在编辑器里检查每个街区并要求修改,然后录制视频。
