Hi Nathan,
You were right, the post was in a forum that should be only used with the Help button below the tutorials. Not a problem at all, as I can move it quickly.
As a side note, the attachment system is broken at the moment, I will send (PM) you an upload link for the image, or a scene file (reduced to the needed minimum, no 3rd party parts please!) Whereby I prefer scene files, images are typically not that informative.
If you use a cloud service, to keep it safe, I click only on DropBox (preferred) or Amazon, Google, Adobe or Apple services.
Here is a tutorial that might answer your questions:

All the best
