Oculus Rift DK2 Camera Offset On Unity3d Emty Scene

Our customer team from Korea 在处理VR与我们的光学大空间定位动补系统的时候遇到一个问题，OCulus VR 怎么处理都存在偏差，Our Japanese chief engineer handling this problem for a whole afternoon ，but give up，最后决定用补偿的方式去处理，无疑增加了复杂度，而且调试出补偿的参数也是很麻烦的一个事情。

After know  the issue,I've checked the Unity3d version, Oculus Rift Driver , Our Tracker System, Empty Project & Current Game, and so on. but i'm still not sure what's the reason.

i just reset the camera position manually.  Import the Oculus Utilities for unity. then call the OVRDisplay RecenterPose Function at start() .

OVRDisplay display = new OVRDisplay();
if (display != null)
{
    display.RecenterPose();
} 

That all.

Note: PC Screen seem to still offset, but it didn't show on Oculus VR Screen
