    For version 1.26 I've found this solution:

     

     

    ovrEyeRenderDesc lerd = ovr_GetRenderDesc(hmd, ovrEye_Left, hmdDesc.DefaultEyeFov[0]);
ovrEyeRenderDesc rerd = ovr_GetRenderDesc(hmd, ovrEye_Right, hmdDesc.DefaultEyeFov[0]);

float ipd = abs(lerd.HmdToEyePose.Position.x) + abs(rerd.HmdToEyePose.Position.x);

     

     


    I'm using a Rift S which has software IPD, so I don't know if it works with older models as well. If you multiply by 1000, you should get to millimetres.
