title: Unity3d floating point precision limitations
body: <p>I got a warning from Unity3D Pro that I don't quite understand.
  I set my player's Transform.position.x to 1000000 in the GUI and it gave me this warning: </p>
  
  <blockquote>
    <p>"Due to floating-point precision limitations, it is recommended to bring the world coordinates of the GameObject within a smaller range."</p>
  </blockquote>
  
  <p>Does that mean that my single scene has to be smaller than 1000000*1000000*1000000. Is this considered big enough? I will need multiple scenes if I want a larger world? When a new scene gets loaded, will my player's position be reseted? How do I manage the position data so that it doesn't go out of range?</p>
