Hi all,

I'm building a system that generates and writes a set of USD layers.
I want to then create another USD layer that references/payloads those layers.

I have a ROP fetch writing the layers so I end up with a list of the file paths in an attribute but I can't see a way to dynamically fill in the multiparm on the Reference LOP.
I've got an expression on 'num_files' with which works.

I fear that it's not possible to do this but I'd love to find a way.
Using PDG and LOPs like this seems like a really powerful workflow.

Thanks!

I managed to achieve what I wanted with a python script LOP but it would be nice to do it with the Reference LOP.
I reckon there are similar workflows that would benefit.
