Built-in rooms or rooms created using the Synthetic Environment Builder are ideal for development and testing, offering data for passthrough, scene, and depth. However, if you only require scene data, lightweight JSON-based rooms are the perfect solution for your needs.

Meta XR Simulator ships with two built-in rooms in JSON format. The JSON files for these rooms are located at: MetaXRSimulator/config/anchors/scene_anchors_room_with_furnitures.json and MetaXRSimulator/config/anchors/scene_anchors_empty_room.json. You can load them into Meta XR Simulator by following these steps:

When SES is running, you will see both the SES environment, and the data from the scene JSON file at the same time. To see only the data from your scene JSON, do the following:

You will now see the scene JSON data independently of the SES environment.

To stop scene JSON, you will need to go to %user%\AppData\Roaming\MetaXR\MetaXrSimulator\persistent_data.json to remove scene_anchor_data from the JSON.

Alternatively, you can set up a room using your Quest device by navigating to Settings > Physical Space > Space Setup > Set Up and exporting it into a JSON file for use in Meta XR Simulator. For details, please refer to Scene Recorder.

If you wish to construct a JSON room, it is necessary to understand the JSON schema. Please refer to Meta XR Simulator Room JSON Syntax for more details.
