I stopped a tiled dense cloud export this AM (3 billion points) that had created ~10 thousand 1km x 1km tiles on a ~500km x ~500m section of coast that's sort of v-shaped. It was 16 hours in and reported >16 hours to go.

Exporting the entire cloud as a single file took ~34 minutes. It looks like maybe there's a "blind" tiling of the region before anything else that generated the 10 thousand tiles when it should only be 500 - 1000 tiles at most? I'm not sure why everything slowed down so much, but wanted to report. Happy to provide more info if it helps.

Hello Andy,

Which version of Metashape you are using? And how the point cloud is oriented in the coordinate system (maybe you can post a scheme or overview of the cloud in XY axis of the geographic system)?

If you have the log related to the export, it could be also helpful.
