Hi Ryan,

In the multi-session tutorial, the odometry was saved in the database. If you recorded data without odometry (just kinect's frames), then visual odometry should be computed, and in your case, the red screen means it is lost.

I suggest to create normal databases with odometry included, then do multi-session on these databases. Another note: if you do only hand-held mapping, you don't need ROS if you rebuild rtabmap from source with libfreenect2 support (so that standalone can be used to record data from kinectv2).

cheers,
Mathieu
