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"

Hi ga4ooo2,

I have a few questions for you.

  • Are you using the binary version of the Engine that is installed by the Launcher?

  • Did you notice anything at all unusual when you were last using the Engine?

  • How do you normally open your projects?

Are your projects completely missing from the Library in the Launcher, or does double-clicking on them fail to open them? When the Engine was missing, was the card for the Engine version you were using no longer present in the Library, or was it there but the Engine would not launch?

This is quite unusual. I just want to make sure I completely understand what you were seeing, so I want to summarize the situation as I currently understand it and if you could let me know if I missed anything that would be great.

You have been using version 4.12 of the Engine, and working on some different projects (were they code projects, or pure Blueprint projects?). The last time you were working on a project everything seemed fine except for some lag in the Editor. You shut down the Editor and Launcher normally, and then shut down the computer normally. When you re-started the computer, the Launcher was no longer present, and the folders where the Engine and projects would have been located were now empty. You re-installed the Launcher, and in the Library section it showed the 4.12 Engine was still installed, but no projects were available.

Would it be possible to get the dxdiag information for your computer? Also, what anti-virus software do you use? Has the anti-virus software reported anything being quarantined/deleted recently?

  4. what kind of information u need from dxdiag drivers, graphic card info... or all and do i put info in comment or send privately?

From discussing this issue with some other people here, it seems as though there have been a few reports of similar occurrences involving the Engine and/or projects in the past, but we have never been able to reproduce them internally or determine what caused them. One person even mentioned a recent experience where his GPU crashed while playing a game, and when he restarted the computer the game he had been playing was completely uninstalled. So it does not seem to be something specific to Unreal Engine 4, but so far it appears to both be very rare and very random.

With regards to your dxdiag information, the more you can provide the better. I don't think there would be any hardware-related causes for this issue, but I want to try to rule that out. You can upload the dxdiag text file here or, if you prefer to provide it privately, you can send me a private message on the forums with the information.
