Imagine if you add a new sfx file to the project, then there is a background process that starts to cook it for upload without freezing the editor, and any action to it while it happens will either cancel the process and restart it, OR restart the process after its done, but again without interrupting work in editor or in live edit. Assets show red in live edit, and after the process is done, they flip to the updated version.
No button presses for live edit or pushing changes, it happens at all times and Fortnite launches and syncs when UEFN does.
This would save so much time when building and in an ideal scenario even make it that we don’t pause work at all when iterating or updating with new assets.
