How to add my own usd into isaac sim?

Hi Toni,

Thanks so much for your reply, still stuck. I got your idea that I should use “add_reference_to_stage” this function, so I change the code as following.

It adds a object to the world as I can see “log” under the frame. But still nothing here, and some error appears in the terminal. Could you please tell me how to fix it?

p.s. I saw your reply in another question about the same question(How to use USD files in Extensions - #3 by yan.mtx) but I still not get how to fix it
