So I have created UStruct in BT\_TaskNode Like that :

```
USTRUCT(BlueprintType)
struct FSAnswerText
{
	GENERATED_BODY()
		
	UPROPERTY(VisibleDefaultsOnly, BlueprintReadWrite, Category = "FSAnswerText")
		FText FTAnswerText;
	UPROPERTY(VisibleDefaultsOnly, BlueprintReadWrite, Category = "FSAnswerText")
		float DelayTime;
};

```

I want to make visible this UStructure and variables in details panel to change its default values but no matter what I do its still blank so what should I do to make it work?

Add “EditAnywhere” to the UPROPERTY(…, EditAnywhere, …) and it should show them.

Do you also use this Tags in the definition of the struct variable itself like:  
UPROPERTY(EditAnywhere, BlueprintReadWrite)  
FAnswerType Whatever;  
and is this variable public?

USTRUCT(BlueprintType)  
struct FSAnswerText  
{  
GENERATED\_BODY()  
public :   
UPROPERTY(BlueprintReadWrite, EditAnywhere)  
FText FTAnswerText;  
UPROPERTY(BlueprintReadWrite, EditAnywhere)  
float DelayTime;

Do you mean something like this?  
even this have no effect at all

No not that you have somewhere inside a class (probably) a variable of that type in order to use the struct thats the part we need to edit i assume.

Yep i think i have to decleare this struct inside of UClass but VS throws me compilation error no matter what I do, currently my code looks like this

 ![203957-screenshot_1.png](https://d3kjluh73b9h9o.cloudfront.net/original/4X/4/2/2/4229edac248aa546948fa571cc046d616a70dcc0.png)

Have you ever done something like this by yourself?

Just make the USTRUCT in a different .h file and include that one into the class that uses the struct.

And put inside the class as a member variable:  
UPROPERTY(EditAnywhere, blueprintReadWrite, Category = “FSAnswerText”)  
FSAnswerText myStructVariable;

Now you can set the struct defaults in the Blueprint/c++ of your class.

For me this always works perfectly fine I expose structs very often I would try remove the public in the struct (this solves the compiler error). But to expose it in the editor you need DECLARE a viriable of “FAnswerText”! Add

```
UPOROPERTY(EditAnywhere)
FText AnswerText;

UPROPERTY(EditAnywhere, BlueprintReadOnly, Category="Whatever")
FAnswerText AnswerText;

```

Structures are not allowed to be initialized without initializing all of its members. You have to add a constructor like this.

```
 USTRUCT(BlueprintType)
 struct FSAnswerText 
 {
     GENERATED_BODY()
 public :         
     UPROPERTY(BlueprintReadWrite, EditAnywhere)
         FText FTAnswerText;
     UPROPERTY(BlueprintReadWrite, EditAnywhere)
         float DelayTime;

     FSAnswerText() : FTAnswerText (DEFAULT_VALUE), DelayTime(DEFAULT_VALUE)
     {
     }
 };

```

Remember to add the DEFAULT\_VALUES, it´s just a placeholder for the answer.

Hope it helps.

I am having this problem and adding a constructor that sets all struct members to a default value has not changed the behaviour.
