I have a bunch of scenes that do weird-stuff to images (every image in a folder...over time) -- each one relies on a different folder and, within each scene, I sometimes refer to the same folder a few times.
I would love to have the option of getting a folder name (full path or whatever) from a global.
SO, for example, I could then duplicate the project and just change the global folder names/paths to update everything to work on these new folders.
Possible? (is there already a way to do this?).
Thanks!

If you put the image folder module in its own scene, then use that scene everywhere you want to use the module, then you only have to change the path in one scene. If you need to change parameters of that image folder module, just set them up as globals then you can change them from anywhere.
