In the following section, we will go over how to set up a new Unreal Engine 4 (UE4) project to work with SteamVR.
If you have not done so already, make sure to run the SteamVR Room Setup to establish and calibrate the VR tracking area.
Failing to do this could result in SteamVR and UE4 not working correctly together.
Create a new blank Blueprint-base project with hardware set to Mobile / Tablet, graphics set to Scalable 3D or 2D and No Starter Content.
Click for full image.
Once the project loads, click on the small triangle next to the Play button and then from the menu that is displayed, select the VR Preview option.
When the VR Preview launches, put on your HMD and you should now see the basic level being displayed and have the ability to rotate your head around in any direction when you put the HMD on like in the video below.
When completed you will be able to view the UE4 project using SteamVR and the HTC Vive HMD.
