Attached camera to camera crane to camera rig rail keeps unattaching itself in outliner

Hi,

I have a level sequence and in that there is a spawnable Camera, Camera Crane and Camera Rig Rail as three separate tracks.

In the outliner I have attached Camera → Camera Crane → Camera Rig Rail so that they are in a hiearchy in outliner.

  • camera rig rail
    - camera crane
    - camera

This kind of works - but when I come back sometime later (~ 1 hr) - they will have detached themselves and the hierachy looks like:

  • camera rig rail
  • camera crane
  • camera

Thanks

When attaching spawnable entities, you need to create attach tracks in the sequence. When you close the sequence your spawnable entities are de-spawned, and any changes untracked by the sequencer (such as attachment hierarchy) are lost.
Ensure the resulting attach section spans the full duration of your sequence.
