Hello!

I am trying a few things but not succeeding through the documentation. What is the way to create in a Python LOP a Reference of a primitive form a usd file in disk?

The same thing with nodes is done using a Reference lop and referencing the primitive through the multi-input from a usd coming through a sublayer.

Thanks

It can also be done quite easily (and efficiently) via Inline USD lop, but I am curious about the python method.

Hi!

Here you can see some examples from Omniverse website:

Hope that helps,

Cheers!

I was using that as my main reference but I was missing one thing and wasn't getting what I expected. I managed to make it work now. Thanks though!
As soon as I find a moment I will post a hip file with the 3 different methods in case it can be of any help to anyone.

Reading the AddReference() documentation it doesn't look like you can add multiple references within it. It would require using a loop containing the function right?

Yes, AFAIK if you want to add multiple references you will need to do it with a loop because the AddReference() is expecting individual reference path and a primpath.

Hi! Here is the file with the 3 mentioned examples if it can be of use to anyone. Each will be useful for different scenarios. In my case, since its part of a larger logic driven by some python in an HDA module, both the InlineUSD and pythonscript lop are the better options. For what I want to do, I feel like the best one is the InlineUSD method.

Cheers!

It has some interesting solutions, thanks for sharing it
