UCameraComponent 를 상속받은 Component 에서 Tick 마다 업데이트될 정보가 있어서 TickComponent 를 상속받아서 구현했더니 TickComponent 가 호출되지 않네. UCameraComponent 소스를 확인해보니 AActor::CalcCamera 에서 UCameraComponent::GetCameraView 를 호출하고 있으니 GetCameraView 상속받아서 구현하니 돌아감.
void AActor::CalcCamera(float DeltaTime, FMinimalViewInfo& OutResult)

// Look for the first active camera component and use that for the view

GetComponents<UCameraComponent>(/*out*/ Cameras);
for (UCameraComponent* CameraComponent : Cameras)
{

{
CameraComponent->GetCameraView(DeltaTime, OutResult);
return;
