Add USD file to multiple environment

[JianlinWang-JL]

I am using isaac omniverse gym and trying to add a unique USD file to the world that has multiple environments (let us say 64).

I am using the following method:

As shown in the figure, I am trying to import multiple logbots and logs into the environment. However, only logbots works here which is also a USD file.

I am very confused, there seems to be no mistake in the log USD file.

I would like to see if anyone has any clues for that? Or is there a better way to import the USD file?

Many thanks in advance for any help!

Yours sincerely,
Jianlin
