I have a scene that has a scale of 20x20 units. But to the player, it should appear as if it was more like 1x1 sized - so something that the player can view from different angles using the 6dof head tracking. I know that I should be scaling the player object (I used it in another test, see here: ), but the GvrArmModel thingie is not cooperating very well since the last time I've used it. Is there a simple way to scale the player's head movement? I don't want to scale the world down, since this would break physics and other things.
