LiDAR scanning needs a LiDAR sensor, which means an **iPhone 12 Pro or later Pro/Pro Max model** (not the standard/non-Pro line), or a LiDAR-equipped iPad Pro. Select **Create a Scan** from a location's map screen, and you'll see six setup tips before you start: * Only scan one room per capture * Scan every surface in the room * Move steadily around the room * Keep your space well-lit * Stay within 3–10 feet of a surface while scanning * Close other apps on your phone for optimal performance Walk the room while your phone builds a 3D model — there's no fixed time limit, it's paced by how thoroughly you cover the space. When it finishes, review the generated floor plan and select **Save** to attach it to the location as a moisture map, ready for readings. A scan can fail partway for a few specific reasons, each with its own on-screen message: the room is too large, the device is too hot, or tracking was lost (usually fixed by better lighting or making sure nothing is covering the camera/sensors). There's no pause-and-resume mid-scan — a failed or cancelled scan needs to be restarted — but if you back out of the screen after a scan completes successfully but before you save it, TrueRestore finds it again and lets you pick up the review/save step where you left off. No LiDAR sensor on your device? TrueRestore will offer **Add Map from Photo** instead — see the next article.
