Vive IPD

Is it some connection between IPD /Vive HMD/ and software IPD /UE4/? I think not. IPD in VR looks unchanged when I using HMD IPD screw.
It should be “automatic” or not?

I’d like to know how to adjust IPD on Vive also.

I’ve tried using the console command stereo e=0.0xx which might be for Oculus only. doesn’t seem to do anything for Vive. also played with the WorldToMeters in World Settings, which only seems to adjust my size. everything in the world still feels too close.
