Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Missing level map

When i open my project i just cant see two of my level maps in the content browser, they are missing! But i open my content folder and their still there. I think ue project is not detecting it up, is there a way that i can refresh my content browser? i tried to clone the project but still the same.

Product Version: UE 4.8

I have the same problem, I can see the .umap file in the content folder but ue4 content browser cant seem to detect it. The reason it happened for me is the my PC shut down while ue4 was running and it might cause some problem saving the map data. Unfortunately i did not find a fix or how to recover the .umap :(

Hello, I have been having the same exact problem as Dash07 often when loading projects after shutting down my computer. It has happened with several projects, but I haven't crashed. The map is accessible through file explorer (I'm on a PC), but when I drag it into the editor I get an error: "Failed to import....unknown extension 'umap'". I also attempted to import the map from within the editor, but it wasn't visible.

Also, I cannot change the 'Default Map' or 'Editor Startup Map' to my map because my map has disappeared from my project.

Ironically, I saved every 30 seconds but did not save a backup.

This might not help Dash07, but hopefully it helps anyone else who runs across this. I had the same issue and was able to "fix" it by deleting the .umap file from \Documents\Unreal Projects[projectname]\Content* and replacing it with the most recent copy found in \Documents\Unreal Projects[projectname]\Saved\Backup.

When I renamed the backup file to match the name of my level, UE4 immediately recognized it, and it showed up in my Content Browser. This copy works without issue.

using4.14 in mac as its the only version that works,,but my map created in PC, doesn't show up under ' open level'

I had to chmod - x the file as it was showing up as a exec in tacos directory, hoping that would fix it.

Any ideas?

Ok, I had this problem too. Last night my project was perfectly fine. this morning, I turn on the computer, load up editor, and discover that the level file I'm working on is missing in editor browser, but not missing in it's folder on my computer. So I located the backup .umap save and replaced the level .umap as drummerof13 described. Immediately I am able to load up the missing level file I thought I'd lost. OK now I have a new problem- when I go to play the level to test it out, I discover that A- I am not being spawned at my player start. B- My third person pawn (Player) is not being spawned at all C- (Probably related to B) I cannot move or control the pawn.

I've tried pretty much everything I can think to do- Restart editor, delete and replace player start, delete and replace thirdpersonBP, etc etc. I am completely lost. any ideas? This issue seems to be too specific to yield any help from google searches...
