Creating for the Meta Quest 3 with Unreal Engine 5

Introduction

The Meta Quest is a head-mounted standalone system, which is a gateway to experiencing digital actuality (VR). It’s now coming into into its third era, often called Meta Quest 3. It may be developed with sport engines — similar to Unity and Unreal Engine — that offer you prepared instruments for stereo shows and movement monitoring.

This tutorial begins your growth for the Meta Quest 3 in Unreal Engine 5 (UE5).

VR platforms are primarily supported in UE5 through the OpenXR API plugin. Alternatively, the Meta Quest XR Plugin offers one other all-in-one plugin for growth on Meta Quest and Oculus Rift headsets, supported by Meta. (This tutorial depends on the OpenXR plugin, as that is the extra generalized system.)

Unreal Engine 5 offers a Digital Actuality pattern mission template which options instruments like a VRPawn Blueprint, implementing avatars for movement controllers, participant motion, and stereo rendering that follows the orientation of the participant’s view.

It’s time to dive into the dungeon within the Meta Quest! Inside this tutorial, you’ll discover the fundamentals of the VRPawn Blueprint, and lengthen the design for personalized interactions. Additionally, you will see how one can make interactive parts — together with grabbable objects, doorways, and switches.

Digital Actuality Template

Unreal Engine 4 and 5 each embody a wide range of usable template tasks that will help you get a leg up on growth for a specific sport fashion.

The Blueprint Digital Actuality Template offers property for creating video games with teleport locomotion, snap turning, and grabbable objects. The beginning pattern mission builds upon this template mission to present an instance for tips on how to adapt content material to begin a VR sport.

Obtain the starter mission to start this tutorial — yow will discover a hyperlink on the prime or backside of this web page!

VR Participant Character

It’s time to evaluation Recreation Mode setup. The Recreation Mode lets you choose the VRPawn Blueprint for the preliminary state of the sport, and offers the fundamentals for a VR expertise.

Open the starter mission in Unreal Engine 5. Then, discover the World Settings tab within the decrease proper of your editor view. Use the Window ▸ World Settings menu choice if it’s not already open.

In Unreal Engine, a Recreation Mode may be assigned to a stage, defining the fundamental guidelines of gameplay. The Recreation Mode may also set the Default Pawn Class, and the preliminary setup for a stage — it units the VRPawn Blueprint Class to signify the participant for the interfaces with the Meta Quest headset and movement controllers.

Subsequent, open the Content material Drawer on the backside of the Unreal Engine editor, and discover the VRPawn Blueprint Class by utilizing the ‘Search All’ discipline. After you discover the VRPawn, double-click to open this within the editor.

The VRPawn Blueprint will open within the Blueprint Editor.

To know this Blueprint, it’s finest to interrupt it down into separate components:

First, discover that the Parts tree comprises each a Digital camera that tracks the head-mounted system (HMD), in addition to the MotionControllerLeftGrip and MotionControllerRightGrip that present visible representations of the VR controllers. Beneath these, respectively, are the HandLeft and HandRight skeletal meshes that reply to modifications within the controller positions and grip actions.

Subsequent, the Occasion Graph and Capabilities present the logic for a way inputs from controller presses can seize objects, or result in motion actions — together with teleportation and snap flip actions. Teleportation is a typical motion scheme supported in lots of VR video games to mitigate detrimental results of movement in VR that may result in nausea.

Within the VRPawn Blueprint, a button press initiates a hint from the present World Location and the Ahead Vector of the proper controller, and attracts a trajectory path to the potential new participant location.

On the button launch, the Strive Teleport block will check if it’s a sound vacation spot, and transfer the participant in that case.

First Steps: Teleportation

So, what’s a sound vacation spot? It’s any floor on the world map that falls inside a NavMeshBoundsVolume, outlined as a navigable floor.

The PlayerStart location is positioned on the entrance of the dungeon. You need to start by including a navigable floor beginning there. You’ll must discover a C++ Class from the Engine. To make these seen within the Content material Browser, discover the settings within the right-hand nook of the browser. Ensure that each Present C++ Courses and Present Engine Content material are enabled.

Seek for the NavMeshBoundsVolume C++ Class from the Content material Drawer, and drag a replica of this class into the world view so as to add to the extent.

Choose the NavMeshBoundsVolume and look beneath the Particulars tab beneath Rework to alter its location as X:955, Y:230, Z:-110, with a Rotation of Z:-45 and a Scale set as X:5.0, Y:10.0, and Z:0.4. This orientation and scale extends the slab of the NavMeshBoundsVolume to utterly cowl the grass floor of the beginning location.

Now, within the outliner, copy and paste this NavMeshBoundsVolume to create one other copy. Likewise, replace the Rework to alter its location as X:750, Y:425, Z:-100, with a Rotation of Z:-45 and a Scale set as X:3.0, Y:3.0, and Z:1.0 to cowl the staircase.

Create yet another copy and paste so as to add a 3rd NavMeshBoundsVolume, then replace its Rework to alter its location as X:480, Y:2000, Z:4.5, with a Rotation of Z:0 and a Scale set as X:10, Y:20.0, and Z:0.8 to cowl the remaining flooring of the rooms above.

Choose the three NavMeshBoundsVolumes and zoom out from the map to see a view displaying that the flooring and stairs are actually contained inside the total volumes, and are actually traversable.

It’s time to present VR a check from inside the editor! Join your Meta Quest by a tether to your PC, and just remember to’ve enabled the tethered connections.

At this level, you’ll be capable of teleport throughout all of the rooms of the dungeon. The Teleportation motion is initiated by shifting the thumbstick ahead on the proper movement controller.

Allow the VR Preview mode by selecting the menu choice within the toolbar.

Click on the inexperienced arrow button to Play this stage in VR and teleport by the dungeon!

Observe: VR Preview isn’t obtainable on MacOS. Nonetheless, you possibly can nonetheless construct rapidly to a Meta Quest by selecting Platforms and both deciding on Fast Launch in case your system is displaying on the listing, or packaging the mission for Android after which putting in to your system with ADB or SideQuest. Skip to the tip of the tutorial for directions on tips on how to get arrange for constructing to your Meta Quest system.
