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"

If you're not using any form of version control, you may have just learned its importance the hard way. Set something up with Git to avoid this in the future. Ideally, if you had version control, you could step back to a version where the Blueprint is working, copy the asset somewhere on your computer, return to your recent version, replace the corrupted one with the working one, and then redo any work that may be missing. It's better than having to delete it completely.

Hi there,

A backup is automatically created (so long as you have autosave enabled) so you can take an earlier version of that asset and overwrite the one causing the crash.

Open up your project's folder in Windows Explorer, and navigate to:


And find an earlier version of the asset (go by date/time), then right click and choose copy on it. Next you need to find the problem asset in your Content folder and delete it (or make a backup), then paste in the file from the Saved folder and rename it to be the same as the deleted asset.

With that done you should be able to open it up again, if not you might need to find an even earlier version in the Saved folder. Some of your changes will be lost, but it should save you a bit of work.

Hope that helps!
