What is BE_CameraRoot in Level?

Hi,
when I prepare target Level map before generates sequences, I want to create a Level contains following actors:

  • BE_CineCameraActor_Blueprint attached to empty BE_CameraRoot actor
  • BE_GroundTruthLogger

I can find BE_CineCameraActor_Blueprint and BE_GroundTruthLogger in core file, but I don't know what is BE_CameraRoot actor.
In fact, I can create LevelSequences without adding BE_CameraRoot actor to Level and render the movie successfully.
I'm confused about it. Thanks

BE_CameraRoot is a basic Actor (Place Actors>Actor) at origin with the name BE_CameraRoot. It is used to setup up a simple camera rig for basic orbiting. It is used for sequences where you want to randomize the camera location/rotation for each sequence for static cameras which are offset from the target center and should face the center area.
See cameraroot option in be_modify_sequences.py for details.
You also need it if you want to create your own project specific orbit camera template for camera movements during a sequence. See #9.
