Update 06 February 2017: Microsoft OneDrive has been added to the list of supported cloud services.
We are aware that many artists and teams are using online storage accounts for their projects. It’s an easy way to work together on the same files and it also has the advantage of being able to access the project from any location.
At the same time, we are aware of the fact that internet connections are not always the fastest thing on the planet. And if your project is already online, it would be a nice shortcut to have it downloaded to our render farm directly from there. So we added support for Dropbox and Google Drive, right in our interface.
