Black dots in imported LAS file
«

Hello
I'm seeing something odd in an import from an LAS point cloud.
There is a band of black dots that seems oddly regular crossing the whole object. When I open the same point cloud in other software I don't see this.
Could it be an issue with the normals?
See screenshot here

Thanks!

Hello rurik,
Is it possible that the normals for these points are inverted?
Can you please try to switch the new to TopXY, select all points and use Tools Menu -> Dense Cloud -> Invert Point Normals command having "opposite normals" option enabled?
