Priorities need tweaking somewhat to help reduce Recap Autoregistration placing things like toilets in the corner of kitchens or inside each other. I also find long corridors can fail miserably as well. Currently work around is to just check before combining groups but would be nice not to have to so much. Maybe readings could be taken from normals more that recognise wall surfaces that should be seen in both scans at the positions it's placed them and if it finds a wall that is only in one scan to not link them? (My programming is terrible so not sure how the algorithms currently work).
Maybe looking for the accuracy on the individual items in a room may also help?
I'm sure you know this is happening but thought I'd raise it on here just in case
