I couldn’t find anything about this in documentation.

How are argument/parameter names specified for custom static functions that are exposed via UFUNCTION to blueprint editor?

for instance:

public:

UFUNCTION(BlueprintCallable, meta = (FriendlyName = "Set Motion Blur", CompactNodeTitle = "SetMoBlur", Keywords = "Set Motion Blue Camera Player"), Category = Camera)
static void SetMotionBlur(UCameraComponent* cam, float amount, float max);

Is shown as:

I would like to have property/argument names show up in blueprint node.

public:

 UFUNCTION(BlueprintCallable, meta = (FriendlyName = "Set Motion Blur", CompactNodeTitle = "SetMoBlur", Keywords = "Set Motion Blue Camera Player"), Category = Camera)
 static void SetMotionBlur(UPARAM(DisplayName="Camera") UCameraComponent* cam, UPARAM(DisplayName="Amount") float amount, UPARAM(DisplayName="Max") float max);

FriendlyName has been changed to “DisplayName”
