An example of how to use Oculus Integration 1.40 in Unity


There have been a lot of changes to the VR landscape in the last few months. As of this writing, there are many tutorials out there today that show how to get started, but each one is slightly out of date. This project pulls together all the things I know about getting a starter project up and running with:

  • Animated hands
  • Thumb-stick locomotion
  • Geometry collision
  • Simple grabbing of objects

Below I have listed each step I've made to create this project. This is the recipe I use whenever I start something new. I'll continue to update this periodically because I am sure that I will be referring back to this often, myself!


  • Unity 2019.1.14f1 - This will probably work with other versions, but this is the version I am working with.
  • Oculus Integration 1.40 - Verify this is the version you're getting from the Asset Store. If there is a newer one out, these instructions may not work. You can find older versions at the Oculus Unity Integration Archive. At the top of the page, where the version number is, you'll find a drop-down arrow. Use that to select the version.

Project Setup

Initially, this was intended to be an example for the Oculus Quest, but except for some specific Android options, the instructions are identical for the Rift and Rift S.

What follows is a step-by-step guide to re-create what I've done in this Unity project.

Start with a new Unity 3D Project. I have not yet been able to get a VR Lightweight RP project to work on the Quest.

Rift / Rift S changes

  • Import Oculus Integraion 1.40
  • Accept the updates (Oculus Utilities, Spatializer)
  • File -> Build Settings -> Player Settings
    • Click Add Open Scenes to add Scenes/SampleScene
    • XR Settings
      • Check Virtual Reality Supported
      • Verify that Oculus appears first in the list, OpenVR is second.
      • Set Stereo Rendering Mode to Single Pass
  • Close the build settings window.

Quest changes

  • Switch the platform to Android
  • Change Texture Compression to ASTC
  • Import Oculus Integration 1.40
  • Accept the updates (Oculus Utilities, Spatializer)
  • File -> Build Settings -> Player Settings
    • Click Add Open Scenes to add Scenes/SampleScene
    • XR Settings
      • Check Virtual Reality Supported
      • Add Oculus to the list.
      • Set Stereo Rendering Mode to Single Pass
    • Other Settings
      • Color space Linear
      • Remove Vulkan from Graphics APIs
      • Set a package name. This can be almost anything you want, but a domain name is the convention. e.g., com.example.demo It doesn't have to be real at this stage, but should be by the time you intend to publish.
      • Set Minimum API level to Android 7.1 'Nougat' (API level 25)
      • Change API Compatibility Level to .Net 4.x
    • Quality
      • At the top, change the default for Android from Medium to Low.
    • Graphics
      • Medium tier - uncheck Use Defaults and select Low.
      • High tier - uncheck Use Defaults and select Low.
  • Close the build settings window.

Scene Setup

The following steps are the same, regardless of the headset.

  • Create a Cube at 0,0,0
    • Rename the cube to Floor
    • Scale the Floor to 10, .001, 10
    • Mark it Static because it will never move. This will cause Unity to generate a baked lightmap.
  • Create another cube
    • Rename it to Pillar
    • Place it at 0, 0.5, 0
    • Scale it to 0.1, 1, 0.1
    • Mark it Static
  • Create a Sphere
    • Place it at 0, 1.05, 0
    • Scale it to 0.1, 0.1, 0.1
  • Create a new folder in Assets called Materials
  • Create three new Materials and name them Red, Green and Pale Blue
  • Set the color of Green to 0, 255, 0
  • Set the color of Red to 255, 0, 0
  • Set the color of Pale Blue to 0, 239, 255
  • Drag and drop Red on to the Sphere
  • Drag and drop Green on to the Pillar
  • Drag and drop Pale Blue on to the Floor
  • Open the Lighting tab
    • Window -> General -> Lighting Settings
    • Under Environment Lighting change Ambient Mode to Baked.

Oculus Integration

Now that we have the basic scene set up, we can start adding the Oculus things.

Set up the Player Controller

  • Delete the main camera.
  • Find the OVRPlayerController prefab. It's easiest to type ovrplayer in to the search field.
    • Drag and drop it in to your hierarchy.
    • Set the position to 2.5, 1, 0
    • Set the rotation to 0, -90, 0


In your hierarchy, expand the OVRPlayerController and find the OVRCameraRig.
Locate the OVRManager panel

  • Change the value of Element 0 in Target Devices from GearVR or Go to Quest.
  • Ensure Use Recommended MSAA Level is checked.
  • Change Tracking to Floor Level
  • Ensure all of the following are checked:
    • Use Position Tracking
    • Use IPD in Position Tracking
    • Reset Tracker On Load
    • Allow Recenter
    • Reorient HMD on Controller Recenter

At this point, build and run your project. You should be able to:

  • Smoothly move with the left thumb-stick.
  • Turn with the right thumb-stick.

Adding Collision Detection

  • Click on the OVRPlayerController in your Hierarchy
    • In the Character Controller section, change the radius to 0.2
    • Scroll to the bottom and click Add Component
      • Add a Character Camera Constraint
      • Check Enable Collision
      • Check Dynamic Height
      • In your hierarchy, expand the OVRPlayerController and find the OVRCameraRig. Drag and drop it in to the Camera Rig field of the Character Camera Constraints script.

Build and run. Now, you should not be able to walk through the Pillar.

Adding Hands with LocalAvatar

I was hoping to be able to use the LocalAvatarWithGrab prefab, but the hands simply do not track correctly for me. As a result, it's neccessary to modify the prefab for the OVRPlayerController.

As of Oculus Integration 1.39, it is necessary to have an App ID for your project in order to display your Oculus Avatar. You can register your app with Oculus on your Oculus Dashboard. Once you have an App ID for your project, you register it under the Oculus menu in Oculus -> Avatars -> Edit Settings and Oculus -> Platform -> Edit Settings

You don't have to make a real project you intend to publish. I've registered a QuestTest application to get an ID to experiment with. Once I'm at the point of making a real app, I'll get a unique one for it. You can also enter a bogus number in like 12345 if you're in a hurry, but you shouldn't. That trick could go away at any point.

Adding the AppID will create three files:

  • Assets/Resources/OvrAvatarSettings.asset
  • Assets/Resources/OculusPlatformSettings.asset
  • Assets/Resources/OculusPlatformSettings.asset.meta

The first two files will contain your App's ID, so take that in to consideration if you add your project to Source Control. These should not be public! I chose to add them to my .gitignore file.

  • In your Hierarchy, expand your OVRPlayerController out until you can see the TrackingSpace underneath the OVRCameraRig.
  • In your Assets folder, find the LocalAvatar prefab.
  • Drag and drop LocalAvatar on top of the TrackingSpace. Do not place it underneath it. If you get a pop-up about modifying the prefab, you've done it wrong. TrackingSpace should expand and you should see a +LocalAvatar at the bottom of its list.
  • Find the Ovr Avatar (Script) component within +LocalAvatar
    • Ensure that Show Third Person is not checked.
    • Optionally, un-check Can Own Microphone because we won't be using the mic in this tutorial.

That's it! Build and run. You should have animated hands.

Making the Sphere Grabbable

  • Find your Sphere in your hierarchy
    • Add a Rigidbody component
    • Add an OVRGrabbable component

That's it for the sphere.

Allow Your Hands to Grab

  • Find LeftHandAnchor and RightHandAnchor under the OVRPlayerController in your hierarchy.
    • Select them both and add a Sphere Collider
      • Set the radius to 0.05
      • Check the Is Trigger box
    • Add an OVR Grabber script to both
    • Check Parent Held Object or you will see some jumpiness when holding and object and moving your hands.
  • Expand the RightHandAnchor and find the RightControllerAnchor under it.
    • On the RightHandAnchor, drag and drop the RightControllerAnchor to the Grip Transform field
    • Under Grab Volumes on the RightHandAnchor
      • Set the size to 1
      • Drag the Sphere Collider of the RightHandAnchor in to this field.
    • In the Controller dropdown, select R Touch
  • Do the same thing for the LeftHandController for the left hand.

When you start up your project now, you should be able to pick up the sphere.

Colliding with Grabbed Objects

You may or may not have noticed that if you pick up the grabbed object and hug it to yourself, or place it under you, you'll be pushed around in the world. To fix this, we need to adjust the collision matrix.

  • Create a new layer called Player
  • Create a new layer called Grabbable
  • Under Player Settings, go to the Physics tab.
    • Scroll to the bottom of the panel until you see the matrix
    • Uncheck the intersection of Player and Grabbable

By doing this, these two layers won't trigger a collision event.

  • Set the layer of the Sphere in your hierarchy as Grabbable
  • Set the layer of the OVRPlayerController as Player. Do not recursively mark all child objects. We only want the top object to be on the Player layer.
You can’t perform that action at this time.
