So we have a setup which uses network storage for all projects however it appears that the Epic Games Launcher only allows vault items and projects to be saved on the same drive as the launcher was installed. I’m hoping this is just a user error and I am missing something obvious that allows project files (most importantly) or vault files to be stored on the network drive rather then local storage.
Perhaps I can be more specific, This feature does not support mapped or network locations that are not windows native. I can use other windows locations on the network but the samba share is not visible, even though it is available to any other program on the operating system.
This may change with a future update to the Launcher, but currently the Vault must be installed on the same drive as the Launcher. Here is a link where other users discussing this same issue and possible workarounds.
