On the PC the KeyVR interface consists of two windows:

  1. The mirror rendering (right)

  2. The desktop UI (left)

Mirror Rendering

In the Mirror rendering you can follow what the user wearing the HMD (Head Mounted Display) sees.

In the bottom of the UI you can choose to hide/attach/detach the mirror view from the UI. You can also go into full screen in which case the mirror view will fill the screen. Press ESC to exit full-screen.

    VR Setup

    This section gives you information about the state of the HMD and controllers. It also enables you to set the mode for each controller to help or guide the user in VR.

    • View mode: Here you can choose between Desktop and VR viewing mode. If the HMD is connected it will default to the VR mode, where the mirror window shows what the user sees in VR. If you switch to Desktop mode, you can control the camera in the mirror window with the same mouse controls as in KeyShot:

      • Tumble: Left mouse button drag

      • Pan: Middle mouse button drag (Hotkey: Ctrl+Shift+Left mouse button)

      • Dolly: Scroll wheel (Hotkey: Alt+Right mouse button)

    • XR mode: Toggles the XR mode. When XR mode is enabled, the environment is replaced with a feed from the HMD’s external camera - allowing you experience your model in your current real-life surroundings. This option only works correctly in combination with an XR-capable headset (like the Valve Index) or an NVIDIA CloudXR setup.

    • Left/Right controller: Here you can choose the current mode for each controller and if needed switch modes. The various modes are described in the section about the VR Interface.

    Image Added


    Here you can select what content, environment and viewing positions is used in the scene - just as you can inside VR via the controller menu. This also enables you to guide the user in VR.

    • Model Set: This enables you to control which Model Set is currently shown in the scene.

    • Camera: All cameras in the

    BIP file
    • scene can be selected via this drop-down list. A click will transport the HMD to that location.

    • Environment: All environments in the

    BIP file
    • scene can be selected via this drop-down list. A click will change environment.

    • Screenshot: During the KeyVR experience you can take screenshots of what you see, these will be stored in the default images folder on your PC

    .Animation: If the BIP file contains animation the animation can be started/paused and reset to start
    • .

    • Scale: Enables you to set your own size in the VR space. The slider lets you scale your own height between 1/1000x and 20x.

    • Units: Set the units used for the Measure tool and Snapping.

    • Snapping: Toggle snapping. Used in the precise move tool, measurements and in-hand object rotating.

      • Snapping scale: When snapping is enabled, you can adjust the scale of the grid it snaps to.

    • Physics: Start or stop the scene physics. Every unlocked object

    • in the

    BIP file
    • scene is interpreted as a separate rigid physical object that can be manipulated with VR controllers in "Move Object" mode. With physics on you can experience the scene with gravity and object collision. When physics are turned off, objects will stay in the exact position where you release them when they are moved.

      • The gravity slider enables you to adjust the level of gravity.

    • Object info:

    • When enabled, properties of the object

    • that the controller is pointing at

    • will be shown, both in the desktop UI and in VR.

    • Animation: If the scene contains animation, the animation can be started/paused and reset to start here.

    • Reset Object Positions: This will reset the object positions and animation to the default values.

    KeyVR Connect

    Here you can start or join a Connect session. Learn more about KeyVR Connect.


    Here you can see the frame rate of the current KeyVR experience. For the best experience the frame rate should always be equal to (or above) the refresh rate of the HMD (typically 90hz). If the frame rate is below that, consider


    reducing the graphics quality


    in the preferences, or reducing the number of polygons in your scene.

    • Quality: The quality is by default set to high. Depending on scene complexity and GPU hardware you may experience low frame rates, in this case you can decrease quality to Medium or Low in order to keep a sufficient frame rate.
