VR Console Commands
Contents
Overview
Unreal Engine 4 has various console commands that effect and interact with various VR specific functionality.
Pre 4.16 these commands followed little structure however now they all start with the "vr." prefix making them easier to document and use.
Although descriptions can be found in the engine I found it easier to have all the commands along with their description in one place.
Commands
General VR Commands
| Command | Description |
|---|---|
| vr.bEnableHMD | Enables or disables the HMD device. Use 1, True, or Yes to enable, 0, False or No to disable. |

| vr.HiddenAreaMask | Enable or disable hidden area mask 0: disabled 1: enabled |
| vr.Debug.bEnableDevOverrides | Enables or disables console commands that modify various developer-only settings. |
| vr.StereoLayers.bMixLayerPriorities | By default, Face-Locked Stereo Layers are always rendered on top of any other layer position types. Set this to a non-zero value to disable this behavior (not supported on all platforms.) |
| vr.Debug.VisualizeTrackingSensors | Show or hide the location and coverage area of the tracking sensors Use 1, True, or Yes to enable, 0, False or No to disable. |

| vr.SpectatorScreenMode (vr.MirrorMode pre 4.17) | Changes the look of the spectator if supported by the HMD plugin. 0: disable mirroring\n 1: single eye 2: stereo pair. Numbers larger than 2 may be possible and specify HMD plugin-specific variations.Negative values are treated the same as 0. |
| vr.HeadTracking.ResetPosition | Reset the position of the head mounted display. |
| vr.HeadTracking.ResetOrientation | Reset the rotation of the head mounted display.\nPass in an optional yaw for the new rotation in degrees. |
| vr.HeadTracking.Reset | Reset the rotation and position of the head mounted display. Pass in an optional yaw for the new rotation in degrees. |
| vr.HeadTracking.Status | Reports the current status of the head tracking. |
Rendering VR Commands
| Command | Description |
|---|---|
| vr.InstancedStereo | Enable instanced stereo rendering (only available for D3D SM5 or PS4). |
| vr.MultiView | Enable multi-view for instanced stereo rendering (only available on the PS4). |
| vr.MobileMultiView | Enable mobile multi-view rendering (only available on some GearVR Android devices using OpenGL ES 2.0). |

| vr.MonoscopicFarField | Enable monoscopic far field rendering (only available for mobile). |
| vr.AllowMotionBlurInVR | For projects with motion blur enabled, this allows motion blur to be enabled even while in VR. |
Oculus VR Commands
| Command | Description |
|---|---|

| vr.oculus.PixelDensity.max | Maximum pixel density when adaptive pixel density is enabled. |
| vr.oculus.PixelDensity.adaptive | Enable or disable adaptive pixel density. |

| vr.oculus.Debug.IPD | Shows or changes the current interpupillary distance in meters. |
| vr.oculus.Debug.FCP | Shows or overrides the current far clipping plane. |
