Placing objects after restarting Spatial Understanding
I'm currently running into a problem. In my app I want to scan a room with spatial mapping and understanding and place gameobjects based on the surfaces in that room. Afterwards I want to be able to move to another room, scan that room and repeat the proces. For now it is possible to scan a room, place objects, move to another room and scan it. However, it is not possible to place gameobjects when scanning the second room. It seems it cannot find any surfaces to place the gameobjects.
The project I am working on is based on the example project in the holotoolkit:
When moving to a new room to scan, I set the SpatialUnderstanding Scanningstate to none and call SpatialUnderstanding.instance.RequestBeginScanning()
Does anyone know how to make the objectplacement work when restarting the SpatialUnderstanding?
