Mozilla Spoke

VR Scene Editing, All In Browser

By Alejandro Romero


Mozilla Spoke is a browser-based environment creating platform for Mozilla Hubs. It allows users to explore images, videos, and 3D models from around the web, import their own 3D models, build 3D scenes in a browser based editor without any downloads or installations, and share their worlds to be explored collaboratively in VR with Mozilla Hubs.

Tutorial: Making and Sharing a Spoke Scene

Getting Started

  1. Go to and click on the blue Get Started button

  2. You will be taken to a screen asking you to create a new project or start the tutorial

    1. The tutorial is great for learning navigation within the editor and learning what is possible. You can quit out of it at any time.

    2. If you select a new project, you can either opt to start a scene from scratch or load up one of the sample scenes

  3. Once you are in your scene, you can add assets from the Assets tab on the lower left corner

  4. You can translate, rotate, or scale the objects either with the toolbox on the top left, or by tweaking values in the bottom right Properties window

  5. On the right side of the screen, over the Properties window is the Hierarchy

    1. This lets you see and select all objects in your scene

  6. Play around with the scene and see what you come up with! If you ever get confused, the Help tab is accessible via the drop down hamburger menu icon on the top left

    1. From here, you can also save your project

Sharing Your Scene

  1. To share your scene, click on the Publish to Hubs button on the top right of the editor. This will prompt you to sign into Spoke with your email

  2. After confirming your email, Spoke will allow you to review your project specs and create a room with your scene

  3. This will generate a room for you! Once you enter, you can invite other users by clicking on the Invite button on the bottom left and sharing the URL or room code with them

  4. Another user can join by going to and clicking the Have a room code? button at the bottom

  5. This can be done both on browser or in VR!

  6. NOTE: If joining from VR, make sure to allow the WebXR experience in the browser (a small banner will pop up on the bottom of the VR browser screen)

  7. You can now see and collaborate with other users in your scene!

NOTE: This entire process, from development to collaboration, can be completed in VR due to its browser-based nature!
