Hello everyone,

I am running into a brick wall with a PDG situation, and I'm wondering if anyone might know a thing about it. What I'm trying to do ought to be simple: I want to load pre-existing images from disk into a TOP network. Here's the current setup with the File Pattern node:



When highlighting a frame and middle mousing the node output, you'll notice that there is no "Output" being assigned



By comparison, if I use a ROP node of any kind and render a new image, there will be an Output



Not having this tagged output seems to have significant implications on the rest of my network, so my question is: How do I properly load images as an output of the node which reads them? Thank you!

Try middle clicking on a work item itself -- that's the typical place to look for output files. I'm not sure why it's not showing up on the node MMB, but a work item is created for each file so I suspect the files will be listed on the work item attribute panel.

Alternatively, it's also possible you configured the File Pattern node to write the file to a string attribute instead of as an output file -- that will also show up in the work item MMB panel.

I should also mention that I've tried toggling "Copy File(s) to Working Directory" as well as using the output file tags + attributes as a substitute for the node's "Output." This, unfortunately hasn't worked.
What I'm ultimately trying to do here is create a mosaic from existing images on disk.
But since the file pattern node does not have an "Output," using this parameter is a no-go:



I've tried changing the file path attribute's "File Tag" to match what Image Magick is looking for, but the attribute isn't really a "File" per-se, and it's not intelligent enough to read the attribute value and go searching for the images from what I can tell.
So I really need these files to be an output of the node rather than a string value.

Hey @tpetrick, thanks for the quick reply,

Here's what I see when middle mousing the work item:

By comparison, with the ROP node, it features an Output:

Ahh, you know what, I just figured it out. Apparently when you check on "Output Attribute" it removes the "Output" from everything.



That was a sneaky little checkbox! Thank you for the help
