​
Start your project

  • Create (or open) a Unity project. Ensure the Unity version is Unity 2021.3 or below
  • Import the URP 12.1.14 package
  • Create a URP Asset in your Project view using Right Click > Create > Rendering > URP Asset (with Universal Renderer)
  • Set the URP Asset in your Graphics Settings by going to Project Settings > Graphics > Scriptable Render Pipeline Settings

​
Create your environment

  1. Use the Unity workflow to design your scene
  2. Set the user’s location and walkable area within your environment: a. Create a GameObject and add the MonoCircularUserAreaProvider component to it. b. Ensure that Gizmos are enabled in your Scene view. You should see a blue avatar with concentric circles around it. The position and rotation of the avatar determine the location and direction the user will start at. The VR Home Screen menu will appear in front of the user when they are in this position in your environment. c. Change the Walkable Radius value of the MonoCircularUserAreaProvider component. The concentric circles will update to reflect the new value. Set this value to match the area you want the user to be able to walk around in. image info
Important Design TipsSince your Unity scene will run on standalone VR headsets, ensure that the scene is optimized for mobile devices.
  • Try to keep your triangle count low
  • Use mobile friendly shaders
  • Bake lighting as much as possible
  • Avoid very complex particle systems with high particle count
  • Try to keep your draw calls/batches low.

​
Validate and export your scene

  1. Go to Unity toolbar > MXR > Scene Exporter. A window titled MXR Scene Exporter will open.
  2. Click on the Validate button. This will validate your scene and violations (if any) in your scene will be highlighted. Click on an issue to expand it. A brief description and any relevant GameObject or Asset will be shown.
    • Issues shown in red will prevent export unless you address them
    • Issues shown in yellow are warnings which don’t prevent exporting but highlight potential compatibility or performance problems.
    • View the list of possible validation issues and recommended fixes If you have no export-preventing issues, click the Export Scene button to export the file ✅

​
Check the size and optimize

Now that you’ve exported your scene, it’s time to verify that the size of your environment is within the recommended size limit of 30MB. Once your mxrus file has finished building and has exported, you’ll see a build report that will show the different assets that have been packaged. Use the build report to verify the size of your environment and identify large assets to optimize or remove: image info
Build Report Tips
  • Click on an asset to highlight it in your Project view so that you can easily locate it.
  • Use the asset type dropdown to review different assets such as shaders, textures, meshes and more.
See the Advanced section for more tips on reducing export size.
