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"

Editor crashes opening a specific level after 4.7.5 hotfix

The primary level we use to test assets in our game crashes the editor as of the 4.7.5 hotfix - even after rolling back in perforce to earlier versions.

What could be the cause?

Hi Sean,

Does this crash only happen with that one level? Does it crash in an earlier version of the engine (4.7.4 or earlier) as well, or do you mean an earlier version of the .umap file?

Can you attach the crash logs for the project after you get the crash in 4.7.5? They can be found in the project's \Saved\Logs folder. If you could also copy/paste the information in the Crash Reporter window when it crashes, that would be useful. Thanks!

Hi Ben,

I'm on the same project as Sean. We've tracked it down to a certain perforce revision of the map that the crash started to happen in. Luckily we can roll back to a previous working version of the map, but obviously we'd rather not have to re-do work. It would also just be nice to know why it's happening as to avoid it in the future.

To answer your questions:

  • The crash only occurs on one specific level in our project, the rest of the maps load just fine.

  • I've tested with 4.7.4 and the crash still occurs, so it's not directly related to the 4.7.5 hotfix.

Unfortunately I'm not too savvy with .logs and .dmps so I've zipped all of the ones that were generated today from the various attempts at loading the map of different revisions. They're attached link text, as well as a text file of the crash window text. It was too many characters to copy and paste. link text

Thanks for taking a look!

Thanks! It looks like a specific asset in the map is causing the crash. Try removing FreeIngredient_Door from the project and then open the map, see if it loads without crashing.

Thanks for helping out - we got to the bottom of the issue. That blueprint wasn't playing nice with the level - likely a version mismatch, we're not sure, but it's fixed :)

Glad that solved it for you! If you wouldn't mind, can you zip and attach the asset for us to take a look at? We'd like to see if it simply got corrupted somehow, of if there's something specific in it that caused the crash. Thanks!
