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"

4.11 preview 7 crashes after saving on successful compiling

So I've done these steps:

  1. Open any BP;

  2. There's a little arrow faced downward near to "Compile" button, press on it and the list'll show up;

  3. Go to "Save on Compile" section and choose "Never" (in case "On success only" is already being chosen, otherwise choose "On success only");

  4. Go to that section again and choose "On success only";

  5. After all previous steps were done, make some minor changes (add any BP node or move some, it doesn't really matter what to do - just make some changes, so you'll be notified by a "star" appearing next to the name of this bp in the tab);

  6. Hit "Compile";

  7. Congratulations! The editor should have crashed after successfully following this instruction.

It's not really a problem, but I do think that this is a bug, so I report that.

I have attempted to reproduce this crash, but I have not experienced it on my end. What operating system are you using?

Windows 7 Ultimate (64-bit).

I can record you a vid with steps, that I've done to make the editor crash.

Thank you, that would help us reproduce the issue on our end. Let me know when you have the video uploaded.

Thank you for providing the video. Can you reproduce this same crash in a clean blueprint, or is it only happening in that particular blueprint? I tried it in a basic actor blueprint, but I did not receive any errors.

Sure, I'll try that after I come back home.

Thank you. Once you have given this a try, let me know the results.

Hm, that seems like a kind of strange behaviour of the editor/engine :D

I even made a completely new blank BP project and this happens:

After some further investigation, I have discovered that we have two bug reports in our system (UE-27856) and (UE-27509) that relate to the issues you were experiencing. Both of these are reported as fixed, and the fixes will be available in a later version.

In the meantime, I recommend saving manually after each compile to avoid running into any issues.

Have a great day
