Pupillary Distance Measurement

[Franka]

I am working with the Vive Pro Eye and Unreal, C++.

Currently I am trying to get the pupillary distance which is set at the HMD, so far without success.

I found a function in SteamVRHMD.h but in the .cpp file it reveals that the "get PD distance" only returns a constant of 64mm.

Then I saw this article https://www.reddit.com/r/SteamVR/comments/g832ug/steamvr_ipd_settings/ that confuses me even more.

Is there any possibility to get PD distance with c++ in unreal and is it necessary to write it to steamvr somehow?

 

Thanks for any help!
