The Unity Free integration for Oculus gives you access to the exact same Oculus features as users of Unity Pro. You can use Unity 4.6 and the Oculus integration package to deploy any sort of VR content imaginable to the Rift!

Once you’ve got your hands on it, getting started is easy. Just import the Unity 4 Oculus integration package into Unity, open the demo scene and get going.

The release supports Windows, Mac, Linux and Gear VR with full access to LibOVR through a pure C# wrapper.

Features include:

High-quality in-editor VR previews

Simple direct-to-Rift rendering

Lens correction, TimeWarp, and dynamic prediction from LibOVR/VRLib

Layered camera support for cockpits, UI, etc

Cross-platform support for XInput controllers

Consistent IPD and head model for comfort at all world scales

Dynamic prediction with the DK2 Latency Tester

Utilities for locomotion, Tracker access, and Rift status

More detailed instructions, tips and tricks are available here. Fellowship and help are available from the Unity section of the Oculus forums.

At Unity we were enthusiastic Oculus Kickstarter backers, and we’re working closely with Oculus to optimize frame rates on games made with Unity and deliver the best possible workflow experience to all our users.

Enjoy!
