VR Editor

The VR tools are available in 3D Settings.

  1. From your model, go to Settings → 3D Settings or add "/edit" to the end of any model URL.
  2. Select the VR panel in the top left.
Only the model's author can access 3D Settings. Edits you make will not change your original file, they will only affect viewing on Sketchfab.

The VR tools in the editor let you configure how your model will be experienced with a virtual reality device. Here, you can control:

World scale

The scale is the most important setting for virtual reality. In VR, you can really have a sense of scale. Just like in real life, you can tell when an object is big or small, far away or near. A 3D car could have the size of an actual car or look like a small toy, so it's important to get scale right.

On Sketchfab, your model remains untouched but you can adjust the scale of the world, represented by the floor and a standard character.

For reference:

  • The character is 1,75m tall (5' 8⅞")
  • Every floor tile is 1m x 1m (3.2ft x 3.2ft)

Adjust the scale until the size of the character looks right compared to the size of your model.

What's the right scale?

Most of the time, you will want to have your model to have the same scale that in real life. But sometimes, this could be impractical in VR:

Very small objects (like a pen or coin) cannot be viewed very closely due to the convergence limit of VR headsets. These models should be enlarged so that detail can be seen at a comfortable distance (~arm length).

Very large objects (like a tall building or mountain) will be hard to view entirely at normal scale. In VR, people can teleport on horizontal surfaces or walk around, but cannot fly around to get an overview of the scene. You can:

  • Downscale to make them look like dioramas, so that people can walk around it
  • Keep their real size, but make sure that the model remains navigable

For medium sized objects, you can scale them like in real life. To make things easier, you can create your model with 1 unit = 1 meter and click the dedicated button to use that scale.

Click Reset Scale to revert to the original world scale.


Mobility in virtual reality can vary depending on the VR device used. Not all devices allow people to crouch or walk in the room. For a good experience, you need to set the floor level so that people can see your model comfortably only by using teleportation and reasonable head movements.

For small models, having them floating at eye level is usually preferable.

You can remove the floor completely by disabling Display floor for teleportation. This is useful for rooms and other large scenes where you only want to be able to teleport around real surfaces.

Initial viewing position

In VR, people can move around by pointing a cursor (imagine a laser pointer) to any horizontal surface and click to teleport there. Teleportation is efficient, compatible with many devices and doesn't make you sick. However, teleportation doesn't work well for unnatural moves, like going through a wall or jumping very high.

Choosing a good initial viewing position is important for people to understand what they are looking at and where they can go.

  • Double-click anywhere in the scene to move the scale figure there
  • Click the scale figure to select it and display the controls
  • Click and drag the arrows to move it along the X, Y and Z axes
  • Click and drag the small blue square to move it freely in the X and Y axes
  • Click and drag the circle to rotate the initial view
  • Click anywhere else in the scene to de-select it and hide the controls

Placing the initial point of view in front of the model works most of the time. This is the default setting.

For rooms, or scenes that are enclosed in a sphere/cube, place the initial viewing position inside the model.

If your scale figure is not standing on the ground, a warning is displayed. Click Move To Floor to automatically place it on the floor.

Once you've made your adjustments, including position and orientation, be sure to update your model's thumbnail image and default position with Save View and/or save your changes with Save Settings. You can return to your model by clicking either the model's name or Exit.

    Great tutorial but wondered if you guys could help... I'm struggling working out what scale I need to use to make the model viewable at a 1:1 scale. I don't like the thought of choosing a scale which looks about right. I know the character used to represent the VR's scale is 1.75m tall but don't know how I can accurately alter this to view the model at a 1:1 scale - screenshot below...

    I know that the model is 1800mm high so the scale is currently set to 1000 as it looks about right but like I said this won't be exact.

    Any help would be great! Thanks!

    Why does it seems like the VR functionallity doesn't work anymore for HTC Vive in the latest Firefox web browser. It was working wonderfully before the the webbrowser was upgrraded. All your instructions are pointing and referring to older web browsers. What can i do to be able to se the Sketchfab objects again?

    @TonyWiren I just tested Firefox 56 (Windows 10) with a Vive and it worked. Can you elaborate on what happens?

    Hey there everybody... Noob here...

    I noticed that we can scale the object when we are viewing it in AR Mode (with the mobile app).

    Is there a way we can lock the scale? And/or maybe add some shadows to the floor?

    There's no way to "lock" the scale, but you can just stop zooming :)

    Shadows would be tricky in an AR environment...maybe in the future!
