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"

"ShowOnlyInnerProperties" in struct does not work with subcategories

I notice that support for subcategories in property list has been added 4.12, i wanted to use them to make struct properties of my object look more cleaner, something like post processing struct has, i could not figure how this was done but now i think it was coded property customization class (i might actually look in to it). In 4.11 i find "ShowOnlyInnerProperties" meta flag which makes struct properties appear as a normal property of object, in 4.12 i tried to use subcategories with it, but when i use subcategory it makes that struct property complitly disappear, i guess subcategory support was not added to that flag, but for consistency sake i consider this as bug :p

Product Version: UE 4.12

Hi Shadowriver,

  • Can you tell me what steps you are taking to reproduce this on your end?

  • Does this occur in a clean, blank project with no additional content or is it limited to one project?

Sorry for late repose, making new C++ projects on my too old PC is pain :p

-First C++ project needs to be created and here the test code i made, this can be pasted in place of default gamemode class (leaving the includes as they are) that is generated with the C++ project, it should work.. at least it worked for me:

 struct FTestStruct{
     UPROPERTY(EditAnywhere, Category = "Test Category")
     FString Value1;
     UPROPERTY(EditAnywhere, Category = "Test Category")
     FString Value2;
     UPROPERTY(EditAnywhere, Category = "Test Category|Subcategory")
     FString SubValue1;
     UPROPERTY(EditAnywhere, Category = "Test Category|Subcategory")
     FString SubValue2;
     UPROPERTY(EditAnywhere, Category = "Another Category|Subcategory")
     FString Hello;
     UPROPERTY(EditAnywhere, Category = "Another Category|Subcategory")
     FString AnotherHello;
 class UBugTest : public UObject
     UPROPERTY(EditAnywhere, Category = "Category", meta=(ShowOnlyInnerProperties))
     FTestStruct Test;

-Then after compilation and opening then project, blueprint needs to be created based of that class

-In blueprint in Class Defaults only Value 1 and Value 2 will apper, only variables that don't have subcategory.

I did fresh project to test the above code and it also occurs in the too. In my original code it was component properties, but i guess this will occur on any property list

To tell the truth i don't really know what is desired result of ShowOnlyInnerProperties is, i find it in FPostProcessingSettings properties of other class as i was searching the way for categories in structs to work, but this we effect of struct varbales visually becoming actor variables been satisfactory for me, subcategory support for this would make things even better

This is still a problem after 3 years.

Hey Shadowriver-

I am not familiar with ShowOnlyInnerProperties either, however the properties not appearing in the editor does sound like an issue. I have entered a bug report as UE-32252 to investigate this behavior.
