Calibrate External Tracking to HMD - Offset between HTC Vive and Vicon Mocap

Dear UE4 community,

we’re struggling for days to solve this core issue of our project and it’s very important. We’re running into an issue with our HTC Vive (HMD + Controllers) and Vicon Mocap through Live Link. Both of our systems are spawning at different world coordinates and create an offset between those two systems.

We’ve found two Blueprints (External Tracking | Unreal Engine Documentation) Calibrate External Tracking to HMD and Update External Tracking HMDPosition
which sounds very promising and could possibly solve our problem.

However, how can we find our External Tracking Transform Blueprint?

Thank you so much for your help. We really appreciate it!
