Say I have a bunch of .csv files each containing point positions and uvs in a folder.

I want to import all that data as TOP attributes and send those to a SOP Add or Wrangle to plot a bunch of points in space. I'm stuck on how to send that to SOPs. How can I call and store those attributes inside a ROP Geometry note, expressions to access a TOP attribute array, etc.

I guess it would be easier to use the table import node, but since it can't be compiled I was hoping a TOP could process the files in parallel, as the .csvs will have hundreds of points each.

You can use TOPs to pass .CSV file to Table Import SOP per work item and merge all resulting geometries

You can do it in TOP Geometry SOP which can automatically merge the geometries of all work items and pass as its output

You set me on the right path, thanks.
