Spawn an actor in front of the HMD view in VR

Hello everyone, i would like to spawn an actor at the height of the player in VR.
So basically i need to get the eye-floor distance and set this to the Z value of the location of the actor.

Unfortunately when i try this on VR it seems it appears a lot lower than it should, does anyone have an idea or some advice on how to solve this issue?

As it seems, the Z transform is always setted at 64 independently from the height of the player with HMD
