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] Blutility Editor Functions vs UEditorEngine


I was wondering if there are plans to improve/increase the Editor functions available through Blutilities.

With the existing functions (https://docs.unrealengine.com/latest/INT/BlueprintAPI/Development/Editor/index.html) I am limited to casting selected actors and running functions on the actors themselves.

I'm hoping to be able to write some editor tools and get some of these functions available:(https://docs.unrealengine.com/latest/INT/API/Editor/UnrealEd/Editor/UEditorEngine/index.html)

  • Spawn/Add an actor to a level (AddActor) - for InstancedStaticMesh bulk batching/optimization, I need to drag my container actor in every time. Beyond this one example, there are a ton of tools that would benefit from this

  • Move actor to a level (MoveSelectedActorsToLevel) When dealing with a ton of assets, it would be nice to be able to move them into correct streaming levels through a Blutility

  • Rename instance (SetActorLabelUnique) the available "Rename Asset" renames the actual .uasset file instead of the instance

  • Replace Actor (ReplaceActors) if I want to do this, I need to drag all replacements into the level, bulk select everything, move the replacements into place and delete the original after doing a cast comparison.

With a few more Editor specific functions, I would be able to write tools to help facilitate level cleanliness, streaming map contents, world outliner readability, automated optimization support tools, etc.

Thanks in advance,

Hi James,

This is a topic that I care a lot about but I'm afraid there are no short-term plans to expose more existing functionality to Blutilities. It's certainly desired and going forward we are trying to build new editor APIs as reflected/Blueprint-aware as they are made.

You should be able to expose most things pretty easily using a UBlueprintFunctionLibrary subclass wrapper, and feel free to submit what you come up with and we'll try to merge it in and maintain it going forward.

Cheers, Michael Noland
