Actor location for packaged SteamVR

Hello,

I am in the last section of my project and I would like to test the project with HTC Vive. Regardless, I have tried to locate camera and starting point of motion controller pawn, I am far away from real location after packaging and trying the game. I will highly appreciate for introductions of usage motion controller pawn for SteamVR . The problem appears regarding the location where I want to be and where I am after packaging the game.
I have added new game mode with motion controller pawn
I edited the default mode to my new game mode.
I set up camera , VRorigin , pawn and root to location where i want to start . ( The desired location to start 0 , 0 , 0 . )
Thanks for any help.
