Sorry, I probably didn´t explain it well (im not a very good english speaker). The problem I mentioned with the camera happens only with the Archviz UI, if I use the VR pawn from the Unreal´s VR template, it works well. And the camera height works well in the Archviz UI, it only went to the floor when I enabled the lock to hmd option (it was a solution that I read in order to solve the problem with the motion tracking of the headset).
