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"

UMG Asset Can't Be Opened if Animation Window is Closed.

Unfortunately I have no steps to reproduce this bug, but one of my UMG assets can no longer be opened. It displays correctly when playing the game, but can no longer be edited.

This seems to happen if you close the animation window in the UMG editor, then close and restart the editor with that same window configuration. At least, that's the only plausible reason since nothing else has changed.

The problem is in WidgetBlueprintEditor.cpp - Line 680. Sequencer is NULL but it's trying to dereference the pointer to it, creating the crash. (Surely this should be wrapped in an If statement??)

The previous entry in the callstack comes from lines 83 > 89, which is wrapped with the comment "If the user has closed the sequencer tab, this will not be initialized". It's obviously clear that the problem is because line 680 does not have the same check.

After some further probing it appears I can't open ANY User Widget anymore, I've rest the UI layout for the engine, deleted all folders other than Content, Config and Source - and still it keeps crashing.

Rolling back and/or updating in Perforce also failed to work - which I figured it would since there were no file changes. Here's an image...

Fixed it by resetting the UI Layout for the editor - However there is clearly an issue here.
