To develop for Oculus 1.3 you'll NEED
to specifically be using Unity 5.3.4p1:https://unity3d.com/unity/qa/patch-releases
You will also NEED
to download the OVRPlugin separately and patch Unity:https://developer.oculus.com/downloads/game-engines/1.3.0/OVRPlugin_for_Unity_5/
Finally, you'll have to update the Oculus Unity Utilities:https://developer.oculus.com/downloads/game-engines/1.3.0/Oculus_Utilities_for_Unity_5/
If you have any questions, please let me know. Thanks.
