In VRED, since not all HMD controllers have buttons in the same location, when in VR or XR, use the controller mode to display tooltips to locate tools.

For a list of supported devices, see Supported Devices.

OpenXR

OpenXR support was added in 2023.4, as it is the new open standard for XR (VR/AR/MR) applications and boosts your experience and works with VR devices, tethered or not. It also includes hand tracking to controller input simulation, so that devices using OpenXR can also use hand tracking directly in VRED.

For VRED 2023.4, not every OpenXR extension is implemented, yet. For example, we currently support several controllers and hand tracking, but it is not yet possible to display the controller-based blue hands, instead of the 3D controller model.

Here is a list of other features are not yet implemented:

• Eye tracking
• AR for OpenXR
• HTC Vive Tracker for OpenXR
• Python support for controller interaction
• Varjo-specific features, such as foveated rendering, marker tracking, quad view, and depth testing

To use OpenXR, simply select the appropriate display mode in the View settings (View > Display > OpenXR HMD).

Selecting a Runtime

To use OpenXR, you must be using the correct runtime. If you are not, a notification is displayed.

To change the runtime, do the following:

SteamVR

1. In SteamVR Settings, select Show Advanced Settings.
2. Select Developer, then Set SteamVR as OpenXR Runtime.

Oculus

1. In the Oculus App, select Settings.
2. Select More and General.
3. Under OpenXR-Rutime set Oculus App as active.

Varjo

1. In Varjo Base, select System.
2. Scroll to compatibility and activate OpenXR.

Vive

1. In Vive Console, select Settings.
2. Go to Advanced.
3. Select Vive OpenXR as current OpenXR runtime.

Controller Bindings

VRED comes with a set of basic tools: VR Menu, Teleport, Tooltips, and the Pointer. By default, these are mapped to the controls on your controllers. See the links that follow for the bindings specific to your HMD's controllers:

• HP Reverb G2
• HTC VIVE
• Logitech VR Ink Stylus
• Oculus Rift
• StarVR
• Varjo
• VRHero/VRgineers XTAL
• WinMR

Managing Controller Bindings for SteamVR

For OpenXR, you can now manage your controller bindings in the SteamVR settings.

1. Go to Settings > Manage Controller Bindings > select VREDPro from the drop-down menu.

2. Set the active controller binding to Custom.

3. Edit the binding.

   Note:

   For the customization of VRED settings to work as expected, it is important that the settings in SteamVR are reset to default (Active Controller Binding = Default). Otherwise, they will overwrite the controller binding setting in VRED

For the customization in VRED controller settings to work as expected, it is important that the SteamVR settings are reset to default (Active Controller Binding = Default). Otherwise, they will overwrite the controller bindings setting in VRED.

Resetting Controller Bindings

To reset all controller bindings to their default values, in the OpenXR tab of the Virtual Reality preferences, press Set To Default.

Configuring a Controller

To configure your controller buttons, do the following:

1. In the Virtual Reality preferences, select OpenXR.

2. Select your controller from the Controller Type drop-down menu.

3. If you want each controller to have different bindings, enable the Left = Right checkbox; otherwise, ensure it is disabled.

4. Open the drop-down menu next to each action and select an option.

   Tip:

   Actions can be disabled, so they are not accessing. For instructions, see Disabling an Action. Controller buttons can also be disabled. For instructions, see Disabling a Controller Button.

5. When finished, press Apply.

Setting Independent Controllers

It is possible to set the left and right controllers independent of one another when setting your controller bindings.

To do this, in the OpenXR tab of the Virtual Reality preferences, enable the Left = Right checkbox.

Adding Additional Controllers

You can add other controllers and set their bindings.

1. In the Virtual Reality preferences, select OpenXR
2. Press Add Controller, then select a controller type from the drop-down menu.
3. Set the controller bindings.
4. When finished, press Apply.

Disabling an Action

To disable an action, so it is not accessible in a session, do the following:

1. In the Virtual Reality preferences, select OpenXR.
2. Select the desired action from the list.
3. Open the drop-down menu next to the action and select None. Now, the action cannot be triggered during a session.

In the future, to make the action accessible, select a target from its drop-down, such as Menu Click or X Touch.

Disabling a Controller Button

Any controller button can be disabled through the OpenXR tab in the Virtual Reality preferences. In the controller bindings list, ensure the button is not assigned to an action. If it is, select another option from the action's drop-down menu.
