Hello, I have a problem when I want to launch the session of my map, it does not work and it marks me failure of validation of the project. Then when I open the error details it tells me “All loads failed with errors.” I recently changed PCs, so I transferred my map to my hard disk to put it on the new PC. At first it worked, but all of a sudden I couldn’t launch the session. I really need help and would be extremely grateful if you could help me.
Is the path to the project folder the same/ correct?
Since I changed my PC, I transferred it to my hard drive and then put it back on my new PC. So it’s not the same one. However, at first it worked fine. The worst thing is that I have access to my map but I can’t launch the session, I hope there’s a solution to this.
Are you using HLODs ?
Are you launching the editor from visual studio? This can give you more insight on what/ where something has gone wrong
No, I don’t think so.
Visual Studio? No, I launch uefn from the epic games store. Is Visual Studio an app to install?

Do a Build Lanscape from the Build menu
Use the Show drop down menu to filter results to see only Red Errors, ignoring the Yellow Warnings
Have you got any red errors ?
Do you have World Streaming enabled ?

Every element on my map has a yellow error, but there is a red error. And as for world streaming, if it’s what I think it is, it’s definitely on.
Don’t worry about the 1000’s of yellow warnings, they’re in every UEFN map, all the props made before some UE update do that.
Theres a start, the ocean… how do you feel about deleting it and putting a new one in ?
I put in a new one, then built the landscape and there were no more mistakes. So I tried again, but it still didn’t work. In fact, it’s saying that it can’t recognize the shortcut path for the map or something.
Here’s the screen of the message it’s telling me
What does the ends of those red errors say ?
LogValkyrieSyncProject: Error: Failed to find public assets [Failed to read C:/Program Files/Epic Games/Fortnite/Fortnite UEFN/cache_cache/Plugins/cache_cache/Content/ExternalActors/cache_cache/1/RQ/DE8I03Q92RFO2ZLDTSJTFH.uasset]
Here’s the complete error
If you put DE8I03Q92RFO2ZLDTSJTFH.uasset in the Content Browser filter does it bring anything up ?
Can you verify the World Streaming, check the World Settings tab see if Enable Streaming is on or off
Your current map size is good for it to be off, but if it is on, it could be an old reference that doesn’t exist anymore
Yes and nothing appears
Yes it is checked.
I tried to leave it unchecked but without success.
Doesn’t matter, leave it checked
