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"

[Critical] - Blueprint Compiler Failing and Freezing Editor


I have managed to put together a blueprint that will freeze the editor if you attempt to compile it - I suspect there is an infinite loop somewhere within the compilation process. I have a working project that can be submitted (contains marketplace assets) to demonstrate this problem.

In the example, all you need to do is plug the following simple statement in construction script into the branch, and the compiler will fail, locking up the entire editor: https://snag.gy/r1hCNa.jpg

Cant reproduce. Error is something else. Provide more info. Crashlogs etc.

You won't be able to reproduce it without the entire blueprint, and I can only distribute that to Epic since it contains marketplace content.

There are no crashlogs and this is as much information as can be provided; the editor simply freezes.

I've somewhat resolved my issue - it would seem that the blueprint is falling afoul of the blueprint iteration limit.

The editor should still not freeze however, in the event of an infinite loop in construction script, it should fail and return to the editor.

Edit: No, it is broken. I'm still hitting this issue even when the construction script event is completely disconnected
