Exception on PointCloud.compactPoints()

[jolle]

I installed Metashape 2.3.0 (build 21954) on a Windows 11 machine.

When I open an a Metashape project with a single chunk with a pointcloud, calling .compactPoints() on the pointcloud gives an exception. Is this function broken in version 2.3?

Code: [Select]

Metashape.app.document.chunk.point_cloud
Out[3]: 2026-02-02 14:51:08 <PointCloud '56220811 points'>

Metashape.app.document.chunk.point_cloud.compactPoints()
2026-02-02 14:51:09 CompactPointCloud: point_cloud = 0
2026-02-02 14:51:09 Finished processing in 0 sec (exit code 0)

Hello jolle,

Thank you for reporting, we'll take a look at this problem.

Meanwhile you can try to use the following workaround:

Code: [Select]

task = Metashape.Tasks.CompactPointCloud()
task.point_cloud = Metashape.app.document.chunk.point_cloud.key
task.apply(Metashape.app.document.chunk)

Hi Alexey,

The workaround works like a charm. Thanks a lot!
