@claywilkinson Thank you very much. I made a low-level error, sfa was not automatically generated by the system.    Model: {      Attributes: [        'Position',        'Color', // do not missing this line,        'Orientation',      ], I am applying AR technology to the CAE industry. The following illustration shows an engine post-processing demonstration in AR. This is a very interesting job, and I am very grateful for the tools provided by Google. If someone encounter the same problem, please refer to my github demo https://github.com/panyingyun/videorecording
