MicroStation to Unity to VR - Workflow 3

The attached PDF describes my Virtual Reality workflow and is meant to replace the two previous tutorials on this same topic. There is some new functionality but the main thing to note is that these instructions relate to Unity 2018.1, SteamVR 1.2.3, and VRTK 3.3.0.

I created a series of companion videos for the original tutorial but they are now out of date. As long as you follow this written VR Tutorial, I think those videos could still be useful as a visual aid. You can find the YouTube playlist here:

The tutorial is split up into simple categories which in a lot of cases can be included in your project on an as needed basis.

Amongst other things, the tutorial covers:
    • Software/hardware that you will need.
    • Download and preparation of the VRTK script files.
    • MicroStation’s surface normals.
    • Creation of collision mesh geometry.
    • Exporting DGN files to FBX.
    • Creating a Unity project.
    • Adding Prefabs and Scripts.
    • Importing FBX files.
    • Adding FBX files to your Scene.
    • Lighting setup for either Realtime or Baked lights.
    • Adding Reflection probes.
    • Making objects grabbable.
    • Adding ambient sound.
    • Creating a floating menu to:
        ◦ Turn ON/OFF different models.
        ◦ Reset grabbable object position.
        ◦ Play/Stop audio.
        ◦ Exit Scene.
    • Build executable code that you can view in a VR headset.

Here’s a screen capture of my Unity environment, it might look daunting but it really isn’t all that bad. VR is truly a game changer and I urge everyone to give it a go :-)

  • Hello VR nerds :-)

    VRTK (Virtual Reality Toolkit) is due for a major upgrade to version 4.0 in about a month or so. In the mean time I thought I’d share my “Space 1999” VR project, all modeled with MicroStation...

    Here is the download link to the latest version: novaclade.itch.io/space1999vr

    The Command Center is a new addition but is not complete. The overall structure is in place but the furniture and computer equipment is missing. I've also moved the scale model of the Eagle to a new scene where you can interact with it in a tailor made environment.

    Here are a few images showing shots from the TV show and my 3D renders for comparison:


    The project is compatible with the HTC Vive, Oculus Rift, and Windows Mixed Reality headsets. To get the virtual environment running on your system:

    - Download the 7-ZIP file from the link above.
    - Unzip it somewhere onto your hard disk.
    - Turn on your VR headset and controllers.
    - Make sure that SteamVR is running as per usual.
    - Using the file browser on your desktop, double click on the “Space_1999.exe” file.
    - Put your VR headset on to view the project :-)

    + The touchpad button is used to teleport all over the scene, including up on top of objects.
    + The menu button is used to turn ON a floating menu and then OFF when you are done.
    + The trigger button is used to interact with items in the floating menu.
    + The grip buttons allow you to pick up and interact with objects.

    There are five scenes which you can access via the top row of the menu. As you explore you can:
    * Spin the globe of the Earth.
    * Pick up the model of the Eagle and containers and transfer them from one hand to the other.
    * Throw the model of the Eagle and containers up in the air (by default gravity is set to moon gravity).
    * From the menu, set the strength of gravity to either Jupiter, Earth, moon or Space.
    * From the menu, change the globe type from Earth to Moon.
    * From the menu, turn the Engine exhaust ON or OFF.
    * From the menu, change the Utility Pods (Crew, Rescue, VIP, None) on the model eagle.

    Have fun exploring :-)
