Spatial Anchors

I like this question because it's a perfect time to ask about this. I think this is a known limitation of Quest inside-out tracking + spatial anchors, especially at your scale (300m² + 10 users).

Common causes of drift:

• Large space → tracking error accumulates over distance
• Low/uneven features (even with posters, still not uniform)
• Lighting changes / reflections
• Multi-user mismatch (each headset builds slightly different maps)

What helps in production setups:

• Break space into zones with anchor resets (don’t rely on one global map)
• Add strong, unique visual features (not repetitive patterns) like the ones you can find on LBE experiences 👀
• Periodically re-align players to a known anchor (soft correction)
• Keep lighting consistent and diffuse
• Avoid large empty floors/walls

For LBE/free-roam, most teams use custom re-centering + correction systems on top of anchors as relying purely on anchors will drift over time.
