Virtual Reality Headset
- In order to run Enscape with the HTC Vive you’re required to have both Steam, including SteamVR installed and running. All required software will be installed by the official Vive Setup.
- Once installed SteamVR will guide you through all the setup steps needed to prepare your room scale VR experience (Run Room Setup).
- Please ensure that the options Allow asynchronous reprojection and Allow interleaved reprojection are activated. They’re available at the Performance settings tab.
- When SteamVR signals everything is green and ready to go, you can go ahead and enable Enscape’s VR mode via the Enable VR Headset button on the Enscape ribbon.
Movement & Controls
- When activating a view or starting Enscape you will be placed on the next valid position on the floor if possible.
- You’re then able to explore your surroundings within the previously defined play-area freely by simply moving around.
- To reach locations outside the play-area press the trigger of the right-hand controller to enable a laser-pointer.
- Use the laser-pointer to mark the location you want to reach and a teleportation-indicator will highlight your target position.
- To activate the teleportation to the marked position release the trigger of the controller and your position will update immediately.
- The laser-pointer is able to penetrate doors and (some) windows (curtain wall windows are not supported yet), so you can easily reach the areas behind them.
- Optionally you can also move around by pressing the track-pad of the left-hand controller. However this is only recommended for users with a certain amount of VR experience, as it often causes nausea.
- The track-pad of the right-hand controller allows you to navigate vertically.
- Time of day may be manipulated by pressing the grip buttons on the left- and right-hand controllers.
- If you prefer to remain standing on a fixed location you may also navigate using the X-Box Controller.
- Make sure that the latest Oculus runtime has been installed and you’ve followed all the required steps of the Oculus device setup.
- Open the Oculus App and select Settings. In the General settings section please activate the Unknown Sources option (For more information please see the official Oculus support center).
- When you turn on your Oculus you should now be able to see the Oculus Home Scene.
- Now you can go ahead and enable Enscape’s VR mode via the Enable VR Headset button on the Enscape ribbon.
- After enabling the Oculus Rift you might not see your Revit project, but a grey image. When you look around you’ll notice a Health & Safety Warning. Please press ‘A’ if using an Xbox-Controller or focus on the button below the warning message to acknowledge it and to proceed to Enscape.
Movement & Controls
- Movement in Oculus VR works just like in regular windowed mode: You’re able to navigate the project either in Walk- or FlyMode using the Keyboard or Xbox-Controller controls.
- Oculus room scale VR and the Oculus Touch-Controllers are not yet supported in Enscape.
- If you’re experiencing stuttering in VR even though your hardware meets the mentioned requirements, you might want to reduce Enscape’s Rendering Quality in the Enscape settings window. Quality level Ultra is not recommended for VR unless you’re running on an Nvidia GTX1080 or better.
- If you have two graphics cards installed make sure either one of them is disabled prior Oculus usage or ensure that Oculus and Enscape are executed on the same graphics card.
Cyber Sickness / Nausea
Usually, if you follow all the above steps and have a powerful enough machine, cyber sickness is not a big problem. However, it depends on the certain person and his/her experience within Virtual Reality. Here is what you can do to avoid nausea:
- The person who wears the glasses should trigger the navigation with a hand controller, not someone else.
- Use flying and elevation rarely, walk physically or teleport whenever it is possible.
- Give the person time to get comfortable with the glasses before handing out the controller. It’s easy to overwhelm new Virtual Reality users.
