Hello, I am experimenting with UObjectLibrary and I think there might be a bug with assigning blueprint actors to such object libraries. I have created a UObjectLibrary in my content browser. Then I select Actor as the base class and enable the flag that it can include blueprint classes. Then I save my object library. I now try to assign a blueprint which is derived from Actor to my object library but it fails to do so. It simply doesn’t assign anything in the object browser. If I do the same with simple Texture2D or StaticMesh (with blueprint inclusion disabled) then I can assign resources without problem to my object library. Is this a known issue or not an issue at all ? Am I not understanding this properly ? The documentation on object libraries is quite scarce. ---

Unfortunately, we do not have a way for the public to track bug reports at this time. However, once it has been resolved, I will ensure to come back and let you know. Have a great day ---

I found some more info that might help. in C++ create a class called UMyObject derived from UObject. in C++ create a class called AMyActor derived from AActor; add a UPROPERTY of type UMyObject\* in AMyActor. in the editor Create a Blueprint based on UMyObject in the editor create a blueprint based on AMyActor in AMyActorBP try assign the UMyObjectBP to the property. it wont work. now in AMyActor change the UPROPERTY to be of type UObject\*. now in the editor try assign the UMybjectBP and it will work. This looks like a similar bug to me than the one with the UObjectLibrary. seems like if the types arent CoreTypes then assignment via content browser isn’t possible. ---

Is this fix included in 4.11 ? ---

This issue has been resolved internally, but the fix will not be released for 4.11. Look for this fix to be implemented into a later engine version. Have a great day
