Spring arm and positional tracking

Hi everyone,

I have a camera attached to a spring arm as I want to use its camera settings. Sadly I am doing something wrong for a while now as I cant get the positional tracking to work.
I feel like I am missing something obvious.

Is anyone here using a spring arm and got the positional tracking running?

  • camera set “lock to hmd”
  • camera manager: “enable camera manager follow hmd” does nothing

thanks in advance for your help
