Hi,

I am using unity 4.6 pro, here i am developing a cardboard application, after import the cardboard plugin from here i just tested my app the cardboard view is coming. But I have given the acceleration in my script that is not at all working. i have tried with different translation eventhough its not working. But it is working in unity5.

I have no idea why its not working in unity 4.6 pro.

Please help me how to solve this issue.
