Have you used revision control to make any snapshots ?
OK The assets and thier positions should be alright, the problem is the landscape.
Using revision control and snapshot history would make it easier, but if you haven’t got any snapshots its a little bit of trial and error to find the landscape assets in the project folders.
If you have revision control on, the first thing to do is Move your islands project folder from User/Documents/Fortnite Projects to somewhere else on the hard drive like C:\projectTemp
Then load UEFN and download the latest backup.
If you haven’t done a check-in with revision control for this project, we need to identify the landscape actors in the project files.
Depending on which scenario your at there’s a few options
Using Windows Explorer find your Project folder in User/Documents/Fortnite Projects/YourMapName and copy it somewhere.
Now the next bit is a little tedious, theres probably a better way, but go into YourMapName/Plugins/YourMapName/Content/_ExternalActors/YourMapName
Now you’ll see a bunch of folders named 0 to F, look and see the date modified and whichever has the latest date is the last one changed.
Each folder in these folders need to be checked for the latest date modified.
Inside these folders are UASSET files, these are the objects in your map.
All the latest date UASSET files need to be moved to a new folder, but keep the folder structure, just in case.
Once you have all the latest date UASSET files out of your project try and launch.
Check-in changes of you do get in
You may be able to just copy a UASSET file from your new folder, straight into UEFN, slowly adding stuff back until it breaks.
Thanks, i did the tedious work of testing each files and after 3-4 hours of testing i finaly fixed the map. I’ll check my changes now and create backup now
I seem to have the same problem. For me it started after activating revisioncontroll. I did the same steps as you and removed all the current files. But I am still getting the error. What I find a bit disturbing is that when I start my card, the v8, it somehow shows that it takes assets from v5, which are 3 versions older. Do you happen to know how I can access my v7? For me all my .uasset had the same day and time of changement so i removed all-
Is it v7 crashing for you, but you can still open v8, but v8 is a v5 ?
Unless you made a snapshot in v5 after switching from v7… that is disturbing…
What I would try,
open v8
select each landscape tile and right click Copy Selected Actor(s) file path and paste it into notepad
use windows to copy all the landscape files somewhere, keeping folder structure
open v7
when it crashes, go into the project folder and remove all the landscape files listed in the notepad
see if v7 opens
if it does open, snapshot it and make a v9
now you may be able to either put the v5 landscape back in
or if you want to try saving the v7 landscape work… you may be able to put the v7 landscape files back in by copying the v7 landscape uasset files one by one in windows and pasting them into UEFN viewport or the outliner. Hoping this way will rewrite whatever was corrupted, or pick up on the error and refuse to paste the corrupted tile, which you could substitute with a v5 tile.
Hey @Hardcawcanary, sorry again for my English yesterday!
I wanted to explain more clearly what’s going on:
I can’t open any version of my map from v1 to v8 – every time I try, UEFN crashes. The issue started right after I activated Revision Control, so I have a strong feeling that it’s somehow related to that.
Even though the error message mentions a landscape issue, the crash only began once Revision Control was enabled – so I’m not sure if it’s a coincidence or connected.
Thanks a lot in advance for any help you can offer!
It may be connected to Revision Control, however I have been using it a long time without issue.
Do you use OneDrive ? it has a tendency to restore stuff without asking UEFN
Increase your Windows paging file to as big as you can get, landscape stuff uses it. It may take some of the load off
Perhaps you can start a new project and copy the maps uasset files from windows and paste them into the new project… I haven’t done this with a whole project, but it might work.
Another thing could be to paste the uasset files into a new project, you will either find the landscape tiles this way or if it crashes theres a problem uasset in the last paste
Once you locate the landscape or problem uasset names, you could return to v8 snapshot and with windows remove those uassets
