JSON is a very commonly used data format so you will come across it at some point. In this video I show you how to get that data into houdini and manipulate your project geometry with it. In addition to this video there is an advanced version of this where I take a look at a more complex json file to extract its data and do funny stuff with it.

    Excuse me, my code is as follow:
    import json
    import hou
    node = hou.pwd()
    geo = node.geometry()
    ......
    but, it shows an error:
    Traceback (most recent call last):
    File "<console>", line 1, in <module>
    AttributeError: 'Node' object has no attribute 'geometry'

    How can I resolve it? Thank you very much!

      geo.addAttribute(hou.attribType.TYPE, "id", 0)

      通常应该在Python节点里使用如上代码，如果是在其他地方，比如Python Shell中，node应该指向一个节点的实例，hou.pwd()返回的是当前执行脚本的节点，如果不是在节点上运行，则返回None，因此下面的代码会报错
