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"

memory references

I am trying to delete an animation blueprint but the editor tells me there are still 2 memory references. I can't find out what the memory references are and the only option is Force Delete.

Here's a list of what I've tried so far:

  • detach animation blueprint from my character blueprint so it's not using it anymore (Use Animation Blueprint: None) and then compile/save

  • "Select Actors Using This Asset" which tells me "No Actors Found."

  • Gone to Reference Viewer (image attached) and then right clicked the animation blueprint (on the left in the attached image) and selected "Show Referencing Objects List" but it doesn't show any results

  • Closed the editor and restarted

If there are 2 memory references shouldn't the "Show Referencing Objects List" show what they are? How can I find the memory references so I don't have to force delete?

Hey there, i get a similar problem sometimes when i had an asset selected as the default value for a certain variable and then i remove the variable. Have you tried closing the engine, deleting the asset (or move it away) and start the engine again to see if he really misses the asset?

I manually moved the animation blueprint out of my project directory and restarted the editor. It doesn't show up in the content browser anymore and I don't see any errors. It looks like it worked, but feels kind of hacky going around the editor and manually moving files in the project directory. Is this a known bug with the editor?

Usually you should try to right click on the content folder and click Fix up redirectors to try to remove pending stuff the engine leaves behind. It's not that unusual to go outside the editor, unreal engine spawns a lot of 1kb files and you have to manually delete them, because they dont show up in the editor. If deleting the asset manually worked please mark the answer as correct and upvote it if you found it helpful :)
