How Can I Hide the Billboard Component in the Editor?

If you create for example a Box Trigger, you can see a Billboard in the 3D Viewport of the Editor. This Billboard is a component, but it isn’t listed in the Component-List within the Detauks Panel of the Editor (see questionmark in the screenshot below).

I am able to create a billboard components, but they are always listed in the Component-List of the details panel.

How, can I make a Billboard Component not appear in the Components-List, to have the exact same behavior like for the Trigger-Box for my own classes:

  • The Billboard itself being visible in the 3D-Viewport of the Editor (see red arrow in the screenshot)
  • The Component not listed in the Component-List in the Details Panel of the Trigger-Actor (see red question mark in the screenshot)

What do you mean be “Not show in the Editor”?

There is a visibility check box, you could unselect it so you will only see it in game.

I’m not sure if that’s what you are asking though.

Are you looking to make a Billboard on your component?

if so: base header

class MYGAME_API UMarkerComp :  USceneComponent
{
	GENERATED_BODY()

protected:
#if WITH_EDITOR
	//A UBillboardComponent to hold Icon sprite
	class UBillboardComponent* BillboardComponent;
	//Sprite for the Billboard Component
	class UTexture2D* SpriteTexture;
#endif

Implementing .cpp

// Sets default values
UAmmoMarker::UAmmoMarker(const FObjectInitializer& ObjectInitializer)
	: Super(ObjectInitializer)
{
	// Set this actor to call Tick() every frame.  You can turn this off to improve performance if you don't need it.
	bWantsInitializeComponent = true;
	PrimaryComponentTick.bCanEverTick = true;

#if WITH_EDITOR

	// Structure to hold one-time initialization
	struct FConstructorStatics
	{
		// A helper class object we use to find target UTexture2D object in resource package
		ConstructorHelpers::FObjectFinder<UTexture2D> Texture0;
		FConstructorStatics()
			: Texture0(TEXT("Texture2D'/Game/MYGAME/Procedural/Blocks/Blueprints/icons/AmmoMarker'"))
		{
		}
	};
	static FConstructorStatics ConstructorStatics;

	BillboardComponent = ObjectInitializer.CreateEditorOnlyDefaultSubobject<UBillboardComponent>(this, TEXT("Billboard"), true);

	SpriteTexture = ConstructorStatics.Texture0.Object;
	BillboardComponent->Sprite = SpriteTexture;

	BillboardComponent->AttachTo(this);
#endif
}

This only works for me if playing in the editor though. If I run standalone game it crashes, so there is another piece to it to really work completely.

Thanks for your comment, I’ve edited the the question to make it more clear.

I am asking for a billboard component visible in the 3D-Viewport of the editor, while at the same time not being shown in the components-list of the respective actor.

Thank You, CreateEditorOnlyDefaultSubobject did the trick :slight_smile:

If you don’t want to use code it doesn’t appear to be possible as of 4.9, but you can add a billboard component then find the default editor billboard and replace it with a transparent png. It’s quite a dirty work-around and I’m surprised it’s not yet a feature.
