Overview

Virtual Reality can be used with the Oculus Rift, HTC Vive, and other headsets which support SteamVR.

  3. Click on the Virtual Reality menu.
  4. Select Enable Virtual Reality and then select the desired runtime for the headset (SteamVR or Oculus).
  5. Prepar3D should now be visible inside the virtual reality headset.
  6. Select Recalibrate Origin to reset the position of the headset to where you are sitting.
  7. The active view can be changed through the Views menu.

Cursor

The cursor in Virtual Reality is visualized by a sphere in 3D space based on the mouse position relative to the Prepar3D window. This cursor will not work if you move your mouse to a monitor that is not displaying Prepar3D. The Mouse Cursor and the Virtual Reality cursor will not be at the same location on the screen.


Config File Settings

There is a VirtualReality.xml file in %PROGRAMDATA%\Lockheed Martin\Prepar3D v4 that saves the Display modes:


HeadsetDisplayMode represents the in headset display mode. OnScreenDisplayMode represents the on screen display mode. In the Prepar3D.cfg, there are two Virtual Reality entries:

Instrument Panels

If an Instrument Panel is opened before entering Virtual Reality, it will be shown in the headset. An Instrument Panel can be opened by selecting the Vehicle menu item and choosing Instrument Panel. Note that not all vehicles have Instrument Panels.


Controls

NOTE: The Virtual Reality cursor must be hovering over the panel to move it.

Developer Mode

Turning on Developer Mode will enable a new headset interface selection in the Virtual Reality drop down menu called HMD Emulator. The HMD Emulator allows Virtual Reality to be enabled without plugging in a headset. Panning can be used to simulate head movement.
