Is this system for sound designers working on games to use, or for players creating mods?
If it’s for developers, I recommend using our source control integrations, instead. They’re already designed to allow sound designers to edit FMOD Studio projects on remote servers.
If it’s intended to be a way for players to submit audio content to to be used in mods, I recommend checking out the Supporting Downloadable and User-generated Content chapter of the FMOD Studio User Manual. It describes ways of letting players create content for your game without giving them free reign over your FMOD Studio project.
I should probably mention that FMOD Studio doesn’t support opening more than five projects simultaneously, which may be a concern, depending on the number of simultaneous users you expect to have.
