I use a SopCreate node to get the geo. inside the node. just some regular process on meshes.
here is the lop net work to compose the usd assets
basically i create a materialX primitive and assign to the geo primitive. for both geo and material i setup the layer path. and finally use a usd-rop to render top level usd file(Aligned.usd)
everything works fine until i tried to work with Tops.
in the Top network, first i use a file pattern to get all old usd file that i need. then i do some attribute create and delete. after everything prepared. i use a ROP USD OUTPUT node to render the usd assets.
here is the error i got
I might have some misunderstand with the ROP USD OUTPUT node.or is it something i setup wrong?
