Hello ric06mor,
Can you please specify, how the problematic point clouds and models have been obtained (fully processed from images in Metashape, imported from external source, etc.)?
Please also specify, if the project has been created and processed in 2.2 version or in some older release versions?
If possible, it would be also helpful, if you can share the archived project.files directory for any problematic project to support@agisoft.com via any convenient file transfer service, so that we could reproduce the problem on our side.
