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"

Project crashes on load after saving

I have been working on a project for some time, it has been open the past 3 days, last night I closed it as the RAM was up to a 3GB after those few days. During those few days, the only things I really edited were 1 BP and few float curves. Today I tried to open it, and got an error message:

I've restarted the launcher, restarted my PC, tried launching project from root folder, and none of this has worked. Any suggestions? Edit #1: It crashes at 94-95% loading, and my RAM usage is around 200MB, CPU is 5-15.

Edit #2: I read some other posts, and I deleted my content folder, it then worked to open my project. After that I re-pasted the content folder, and deleted everything except my main BP folder. It also worked again, so apparently some other asset it causing the problem, but now I have another very bad problem, clicking or right clicking on my MOST IMPORTANT blueprint in my project will cause the editor to crash. How can I get my BP back? It has lots of math and algorithms, so I can't simply remake it.

Edit #3: I've figured out that all of the autosaves before 2 hours after I saved and quit work, and unfortunately all of the stuff I got done happened during the 2 hours. Still need a way to get my most recent BP back.

Product Version: UE 4.7

Can you post a copy of your crash logs here? You can find those at \Unreal Projects\PROJECTNAME\saved\logs\
