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"

[Closed] Default value of custom structure in blueprint corrupts project.

I'm using 4.7 Preview 3 right now. I have a custom structure using three variables: an enumerator entry, a class of a blueprint which has another blueprint I made as parent class and a userwidget. Everything seems to work until I go to my blueprint called "Database" (a simple actor for storing data, read-only) which has an array variable using this structure. I need to fill the default value of it with data. I tried using other methods but they resulted in problems and that's another issue and default values should not cause troubles so I stay with that approach. When I close the project and reopen it, I get this:

Previously the variable was just disappearing when reopening the project until I compiled the database blueprint. But now I either have to delete and redo half of my widgets and blueprints or use a backup version. I hope this can be fixed somehow. Let me know how I can help. I can send you the project, I just don't want to make it available for everyone. Thank you in advance!

Hi DasMatze,

I haven't been able to reproduce this behavior, but I may not be setting it up correctly. Does this happen in a new project, or only your current project? If you're able to set up a small test project in which this occurs, please upload it somewhere and let us have a download link. This would be preferable to your whole project, as it will be easier for us to debug.

Also please zip and attach the crash log you get from this. Thanks!

Problem is not reproducible or outdated


1 answer: sort voted first

I tried cloning the project and deleting everything unnecessary but it appears I cannot reproduce it either. There might be too much connected to this error. I better close this and try to catch the needed data via data tables even though 4.7's data row editor doesn't seem to support asset values at this time.

Sorry if I wasted your time.

It's not a waste of our time if it helps you! If you're able to reproduce this reliably, please let us know and we'll continue investigating. Thanks!
