How do I scan complex rooms with the Metaroom Scan App? 

The Metaroom Scan App supports scanning of complex room layouts, including: 

• L-shape.
• Trapezoid.
• Curved walls*.
• Spaces up to 150–200 m² per scan section.

* In the current version, curved walls are represented by single straight sections. 

The process of scanning complex rooms is the same as for all other rooms. Follow these steps to scan a room with complex geometry:

1. Open the Metaroom Scan App on your iPhone Pro or iPad Pro.
2. Tap the Add Scan button.
3. Follow the pre-scan recommendations:
   • Clean your device lens.
   • Close doors and windows in the room.
   • Open curtains and blinds.
   • Move objects apart to help the app detect them individually.
4. Start scanning from a clear corner of the room, making sure to capture both the floor and ceiling.
5. Follow the guidance as you scan:
   • Keep your distance from walls and objects.
   • Move at a moderate speed.
   • Your movement pattern should always follow the shape and layout of the room for the best results.
   • Important: as you walk around the room, follow its shape and scan in a circular path — this helps you close the loop. To finalize the scan, return to your starting point.
6. Keep an eye on the 3D model preview at the bottom of the screen to make sure all walls and objects are being captured.
7. Once you’ve finished scanning the room, tap Finish Section.
8. On the review screen, check the 3D room model. If anything is missing, tap Rescan to start over. If you’re satisfied with the result, tap Finish Scan.
9. Great work! Keep the Metaroom Scan App open while the model uploads to the Metaroom cloud. Depending on the room size and your internet connection, this usually takes a couple of minutes.
10. Once uploaded, you can access your 3D model from the Metaroom Scan App → Projects, or from Metaroom Workspace → Projects.

Essential scanning tips

1. Keep the camera clear: Never cover the camera when moving between rooms. It constantly tracks your position, ensuring seamless room stitching. Covering the camera will result in losing crucial “world tracking data”. 
2. Hold the device upright: Always keep the device upright, even when not actively scanning, but moving to the next room. Continuous camera tracking allows the app to stitch rooms seamlessly. 
3. Close doors for optimal scan results: To ensure accuracy and completeness, close the room doors.

Pro Tip: to get even better results, we recommend enabling Tracking Assistant in the Metaroom Scan App — it provides real-time guidance throughout the scanning process to help you achieve precise and accurate results.
