Disabling automatic camera tracking in AR

I’m building an AR based project. Currently I’m using the the default Handheld AR Blueprint template for testing. I do not want the device tracking applied directly to the camera–I need to do some bits and pieces to it before the camera gets it. There is an option in the AR Session Config “Enable Automatic Camera Tracking” the help text for which reads “Whether the game camera should track the device movement or not”, which sounds like exactly what I need. However, it toggling it seems to have no effect.

I’ve tested this on 4.21.2, 4.22.2, and the latest Google ARCore build which is 4.21.2 with ARCore 1.7.

So, a couple of questions:

  • Does anyone know if this option should do anything (ie. is it implemented, has anyone had it working before, does it actually do something else and I’m misunderstanding it)?
  • Assuming it doesn’t work, what is the next best way to prevent the tracking being applied to the camera?

I solved this. In case anyone else is looking for the answer, the simplest solution it to turn off “Lock to Hmd” on your camera component. I haven’t dug deep enough to say if this is the best answer, but it’s certainly the easiest.
