Choose your operating system:





One of the first things you will need to think about when starting to develop any UE4 powered VR experience to be used with the SteamVR is deciding whether the experience will be a seated one or a standing one. In the following How - To we will take a look at how to set up your UE4 projects VR camera for a seated SteamVR experience.


Below you will find instructions setting up a Pawn to work with a seated SteamVR experience.

  1. First, open up or create a new Pawn Blueprint and then go to the Component section of the Viewport tab. From there add the following two components with the following names, making sure that the VRCamera is a child of VRCameraRoot:

    Component Name







    No matter what VR HMD you are using, this is the Epic recommended way to set up a VR camera as it allows you to offset the position of the camera without having to move the actual camera.

  2. Next, open up the Pawn Blueprint if not already open and in the Event Graph drag off the Event Begin Play node to show the Executable Actions list. In the list search for the Set Tracking Origin node and click on it to add it to the Event Graph.

  4. Next, in the Variables section of the My Blueprint tab, create a new Vector variable called ViveCameraHeight and set the Z value to 121.


    For a seated SteamVR experience, you will always want to set the height of the camera to match the real world seated height of the user in Centimeters.

  5. Then, drag off the output of the Set Tracking Origin node and search for the Set Relative Location node, selecting the SetRelativeLocation(VRCameraRoot) option.
