If I select all the directories that are created by tooll under the Export directory, and copy those, I get a distributable that runs, but the size is over 200 megabytes. So, it seems there is maybe something missing from the exported release, that gets added when I copy the contents of these directories by hand? Again, when running Player from the exported directory, I get sound but a black screen. I tried to select the Final Output operator along with the project's scene operator that connects to it, but with these selected Export selected is disabled in the File menu.
Also, how do I set the path of the soundtrack to a relative path within the release? When I started work on this project, I drag & dropped the soundtrack file into tooll. However, it seems this is hard-linked now - if I move the file around on my file system and it is no longer in the same location, I can not run Player at all. I tried to look in the main scene .mop file, but the location is not defined there. Where?
