Achieving Consistent Spatial Alignment in Multi-User VR on Quest 3

We’re developing a multi-user VR experience where a 1:1 virtual environment needs to align precisely with a physical space, allowing users to move freely within both. However, we are encountering alignment challenges with the Quest 3 when using the tracking origin modes:

1. Floor Tracking Origin: The virtual environment’s center and orientation follow the headset’s position and orientation, causing misalignment with the real-world environment as the virtual space shifts based on the user’s location.

2. Stage Tracking Origin: Alignment depends on the headset’s orientation and position when the boundary was first created, meaning each device must be set up identically, which is difficult to maintain across multiple users.

Requirement:

• We need a solution to lock the virtual environment to real-world reference points, ensuring consistent alignment regardless of individual headset setup variations. The goal is for virtual and physical spaces to coincide accurately across multiple devices.

Comparison with Other Headsets:

• Devices like the Pico 4U and HTC F3 handle this alignment issue effectively, although the Quest 3 offers a superior overall experience. Resolving this alignment problem is essential for us to continue with Quest 3 as our primary device.

Request: Could you suggest a method within the Meta/Oculus SDK (e.g., MRUK or spatial anchors) to achieve stable, consistent alignment in a shared VR space on Quest 3? This solution would significantly impact our decision to proceed with Quest 3 for this project.
