No imagery when using custom usd

[shojint]

Thank you very much for your work.

I have tried the example scene, and it worked perfectly. However, when I used my own usd, there was no image.

Sometimes this error kept appearing:

I would appreciate your help. Thank you.

Hi, could you describe the changes you made?

I assume you are using a custom USD file, and replaced the example ply file with your own?
