Syncing a world partition level so it updates external actors (SVN)

Hi all,
How do I sync a world partition level, that’s using One File Per Actor within the editor?

With UE4, I was able to right click on a level and sync it no problem with the editor. That would update the level for me with any changes that were made by someone else and reload it as well. In UE5, I’m using World Partition and OFPA. Syncing the level or level folder from the editor, doesn’t update the external actors. I have to sync the WHOLE content folder (which reloads ALL of the files within the project) and only then do the changes come in. Is there a quicker way to sync the level so it updates the external actors as well, within the editor?

Hi. Did you find any solution? We’ve got the exact same issue.

I’d also like to know this. The ExternalActors folder is not visible in the content browser and cannot be selectively synced.

Sadly I haven’t been able to find any solution so I’ve just been updating from source control. :confused:

Didn’t found solution either, just want to make some refresh and attention notice for Epic devs.
It is still a problem to use “One File Per Actor” with source control inside Editor. Currently UE 5.7.4

To reproduce:

  1. Use two computers, connect both to source control (SVN Subversion used)
  2. User 1: create map with World Partition and One File Per Actor. Save, use UE Revision Control panel for “Submit Content”.
  3. User 2: use external source control soft client (TortoiseSVN) to load new level from repo. In Editor change any actor on that new level. Save, use UE Revision Control panel for “Submit Content”.
  4. User 1: Try change or refresh that actor - green arrow will appear (check screenshot).
    So now you can’t really do nothing inside UE to get those changes from User 2.
    You need to load different level (unload/unlock current), use external soft (TortoiseSVN) to update your project, load back UE level.
    Only then you get updates. Green arrow still be there before you manually click “Refresh” on icon.

So as you see this is actually not very convenient.
Please correct me I’m wrong. I guess there should be “Sync” button available for selected actors in Outliner. Right now you only can “Sync” entire project with RMB. Not sure that even that will do the work, becuse it is too long.
Thank you.
