Hello mates! just want to share something usefull that I found very interesting (I hope not braking the rules in here in any way. In that case letme know to delete). There is an old tutorial here to match camera in case you want to start from scratch inside Houdini and model the buildings inside Houdini or there is another scene you want to replicate https://www.youtube.com/watch?v=-WM2hPerYts&list=PLc3Md5247CjP6uxMujBhoy5CXIsQIyMGH&index=1&t=1007s

你好伙计们！只是想分享一些有用的东西，我发现非常有趣（我希望不要以任何方式破坏规则。在这种情况下，让我知道删除）。这里有一个旧的教程，以匹配相机的情况下，你想从头开始在胡迪尼和模型内的建筑物胡迪尼或有另一个场景，你想复制https://www.youtube.com/watch? v=-WM2hPerYts&list=PLc3Md5247CjP6uxMujBhoy5CXIsQIyMGH&index=1&t=1007s

With all that said you can follow alone and start modeling from scratch inside Houdini
