Problem: In Content/Maps/ map is missing. However, it is visible in explorer. The file exists.
It’s part of several levels streamed together. The other levels appear working. Loading the levels and streaming to missing loads nothing. Opening Levels tab in the persistent shows it listed, but grayed out.
We are using Perforce. I’ve tried forcing sync. Deleting levels and forcing. Deleting CachedAssetRegistry.bin and restarting. And making new level with same name.
No results thus far. Level still loads as intended for other users on different PCs.
UPDATE (7/12): still not working. I am able to revert back to my local last check-in, and that appears/loads as normal, but at this point we can’t revert back that far. Project near complete, and many other changes made.
Is it possible that there is a engine version discrepancy between you and your other project members? Usually if a .uasset isn’t visible in a project it’s due to it being saved in a later version of the engine.
One thing to try would be to create a new project and put the .umap in question in its content folder. If it appears in the Content Browser, migrate the .umap from the new project to your existing one using the editor’s content migration tools.
If it is working for other members, have you tried creating a new workspace for the repository and getting the entire project fresh?
It’s a bit of a stretch but one thing to try would be to look for assets that may of been referencing this map and removing said assets. After that, manually place the map into the content folder and see if it may appear then. Unfortunately there isn’t anything else I can think of at the moment without seeing the project.
We haven’t heard from you in a while, ChrisHolden. Are you still experiencing this issue? If so, please let me know if you would be able to provide some more information to help reproduce this issue. In the meantime, I’ll be marking this as resolved for tracking purposes.
Same thing happened to me so I check Mathew J’s suggestion and it worked! Apparently I was trying to migrate a level from 4.20 to 4.19 and that could be the reason why the level won’t show. Made a new project in 4.20 and migrated the level again, and this time it showed. Thanks for the answers!

I am trying to migrate a map and its associated assets to a new project to trim down file size. The current project is in 4.21.2 and the map loads fine in the current project. I migrate the map to the new blank project using the same engine version and the map is not visible in the content browser (but it is listed in the file explorer). If I try to drag the umap file into the content browser I get: “Failed to import: (directory location) Unknown extension ‘umap’”
Wow, I found a fix for this by creating a new level and then naming it the exact name of the missing level. The editor will error saying it already exists and then it will appear in the content browser… rofl
I have the same issue, migrating map and sequence to reduce the size of my project. Both projects run on 5.2.1 and this one map file doesn’t show up in the editor. File exists in the explorer, in the actual file structure. Tried the trick with creating a new level with same name, notified me that it already exists, therefore it can’t create it but nothing showed up. It is not the first time I experience this error and it’s driving me nuts… I could reduce the project by half but it refuses to work so I have to keep unnecesarily big projects. Wish there was a simple way of reducing a project like in After effects for example (you click what levels you want to keep and it reduces everything not related to them).
