I've recently started exploring Motion and when I did the full studio 2 install I placed the media on an external HD that also serves as a scratch disc for FCP. FCP uses it and see's it as a scratch disc. The drive does have media folders that were installed that have Motion's templates and emitters ect.
I did go into Motion's preferences and think I set a path to this folder for templates. I can drag and drop from the folder to the canvas. Any ideas why my gallery still comes up empty?
