Adding multiple instances to instance static mesh component in a code class causes an ensure to trigger when an instance of the class is added to the level.
USphereComponent* SphereComponent = CreateDefaultSubobject<USphereComponent>(TEXT("RootComponent")); RootComponent = SphereComponent; UInstancedStaticMeshComponent* ParticleVisualization = CreateDefaultSubobject< UInstancedStaticMeshComponent>(TEXT("ParticleVisualization")); FName Path("/Engine/BasicShapes/Sphere"); UStaticMesh* sphereMesh = Cast<UStaticMesh>(StaticLoadObject(UStaticMesh::StaticClass(), NULL, *Path.ToString())); ParticleVisualization->SetStaticMesh(sphereMesh); ParticleVisualization->AttachTo(RootComponent); ParticleVisualization->AddInstance(FTransform(FRotator(0, 0, 0), FVector(-5.6526e+07, 5.6523e+07, -3561.12), FVector(0.4f, 0.4f, 0.4f))); ParticleVisualization->AddInstance(FTransform(FRotator(0, 0, 0), FVector(-5.68537e+07, -4066.15, 5.68518e+07), FVector(0.4f, 0.4f, 0.4f))); ParticleVisualization->AddInstance(FTransform(FRotator(0, 0, 0), FVector(-5.77781e+07, 32644.8, -5.77864e+07), FVector(0.4f, 0.4f, 0.4f))); ParticleVisualization->AddInstance(FTransform(FRotator(0, 0, 0), FVector(-5.81239e+07, -5.81233e+07, 15821.5), FVector(0.4f, 0.4f, 0.4f))); ParticleVisualization->AddInstance(FTransform(FRotator(0, 0, 0), FVector(-56.2229, 11.118, 199.461), FVector(0.4f, 0.4f, 0.4f))); ParticleVisualization->AddInstance(FTransform(FRotator(0, 0, 0), FVector(5.65258e+07, -5.6523e+07, 4072.48), FVector(0.4f, 0.4f, 0.4f)));
Result:
Ensure triggers when the instance is dragged from CB into the viewport
