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"

UE 4.10.4 Crash On Project Startup

Upon some research, I believe that my issue could be due to a recent power outage, but it still doesn't help me identify exactly what the issue is. I'll link and image to the error message that I received

https://gyazo.com/80a046d9498159c113da3856573fcfb4

Once I reach 73% of the file to be loaded, it crashes immediately. I've read similar threads about the issue but nothing seemed to help. I've been working on this project for some time now - it would be pretty awful if I there was no way to recover it from it's latest state.

Product Version: UE 4.10

Hi G0dsl4yer,

This is an Out of Memory error and is likely caused by your project file becoming corrupt in the recent power outage you described. However, while not guaranteed, here are a couple of things you can try in order to recover your project:

  • With Launcher closed, make a back up of your entire project file and copy to your Desktop (My Documents>Unreal Projects> [Your Project Folder]) *Keep this in tact in case you need to revert to this version

  • In the original folder (In My Documents>Unreal Projects), delete the Intermediate and Saved folders

  • Open Launcher and try to launch your project

  • If this does not work, close Launcher and try the folloiwng:

  • With the Launcher closed try double clicking the .uproject file to launch the editor

  • If this does not work, follow the remaining steps:

  • Copy the name of the .uproject (project) file

  • Delete entire project folder from (My Documents>Unreal Projects)

  • Create a new blank project of the same type as the original and paste name to be sure it is named exactly as the original project (Be sure to use same Engine Version: *4.10)

  • Close the Launcher

  • Open the newly created project file and delete all folders, leaving only the .uproject file (named the same as the original)

  • From the copy on your desktop (from previous step), copy only the folders (not the .uproject file)

  • Paste folders into the newly created project folder (My Documents>Unreal Projects) *Note all directories must have the same name for this to work

  • Open launcher and launch project

  • I can confirm this works with simple projects, mainly just transporting assets. It may not work for more complex projects but would at least be a better recovery point, if it opens, with all custom assets in the Content Browser

Let me know if this works. If not, you still have the original, untampered with folder to copy back to the Unreal Projects folder for further troubleshooting.

Fortunately, I was working with source tree. So while I did lose a lot of progress, it was better than starting from scratch, so I ended up reverting to an older source point. I did try your suggestions because I read those on another thread but they didn't end up working. No matter what I would load to the same % and it would crash. But I'm in a better position now, thanks for your response.
