Wrong NeckToEye distance for GearVR

Sorry for the question, but how exactly is the syntax of the command inside the “Execute Console Command” BS?
I’ve tried he following inside the level-BS:

stereo ps=0.1
stereo ps 0.1
StereoPs=0.1
StereoPs 0.1

but nothing seams to be executed.
Plus I’m using a Vive to quickview in VR from the Editor and the commands don’t work inside the Vive either.
Is there a specific node/order where the command need to be placed to work?
