What is the download link in the submission detail page used for?
As a submitter, you may decide to store your scene files, or any other files relating to The Sphere Project, on our server. This is especially useful if you have numerous submissions and you wish to keep the data files for each scene safely organized. Files do not have to be scene files – they can be tutorials, shareware plugins, models, etc. You have the option of sharing your files with other users and we encourage everyone to do so.
