Hi all,

I just want to ask something regarding loop closures in 3d lidar-only version. I want to create a lot of loop closures on the graph. How can I create loop closures between nodes while registering the new cloud to the 3d map and 2d map? I saw that if we create a loop closure, it won't register a new cloud on the final cloud like this.



As shown in the picture, the latest node won't update 2d map, so the 2d map is still dotted.

Thank you.
