If you want to enforce that the only practical way is to set up a second workspace with a File/Pathname reader, have it read the directory with OBJ files and then use a WorkspaceRunner to run your existing workspace on that OBJ file only.

Just curious, is there a reason you want to process them one by one?

Thanks for replying. Since I have thousands of OBJ files to process and not to much RAM unfortunately, it takes forever to even just read the first file....

I don't want to seat around and wait for it to finish - I'd like to grab the output and use it as soon as it is ready instead of waiting for the entire process to end.

Here's how I want the workbench to look like except I don't want to duplicate the same Transformer thousands of times to achieve that (like I did here for the sake of example).

Thanks,

Tomer
