Validate Assets

You can use IsDataValid to generated BP compilation message/warning/error as you need (for example, to tell your designers they missed something).

Fix actions

In 5.5 there is a new “fix me” overridable methods that will run code when you click on the text (similar to engine “fix” clickable text), more info here.

Example:

TSharedRef<FTokenizedMessage> Message = FTokenizedMessage::Create(EMessageSeverity::Error);  
Message->AddToken(FAssetNameToken::Create(GetPathNameSafe(Blueprint),  
    FText::FromString(FString::Printf(  
       TEXT("Prefab Reference Component %s doesn't have the default required struct FPSRequiredActorPrefabSpawnParameters (Required Spawn Prefab Parameters)."),  
       *FU_Utilities::GetNameWithoutTemplateSuffix(PRC->GetFName()).ToString()  
))));  
  
// Make a FixeController, this can container multiple fixs
TSharedRef<FMutuallyExclusiveFixSet> FixController = MakeShareable(new FMutuallyExclusiveFixSet());
 
// fix function  
TFunction<FFixResult()> ApplyFix1 = [PRC]()
{
    ...
    return FFixResult::Success();
};
// fix function
TFunction<FFixResult()> ApplyFix2 = [PRC]()
{
    ...
    return FFixResult::Success();
};
 
// action message with fixer 1
FixController->Add(INVTEXT(
	"Click to apply fix1"),
	MakeFix(MoveTemp(ApplyFix1))
);
 
// action message with fixer 2
FixController->Add(INVTEXT(
	"Click to apply fix2"),
	MakeFix(MoveTemp(ApplyFix2))
);
 
FixController->CreateTokens([Message](TSharedRef<FFixToken> FixToken)  
{
	Message->AddToken(FixToken);  
});
 
// finally, add the message to the editor validator entries  
Context.AddMessage(Message);
