"Empty camera list" error after exporting chunk to new .psx project

[Lucas]

Hi,

I’m encountering an issue when working with exported chunks.

Workflow:

I had a larger project with multiple chunks.

I exported one chunk into a new .psx project file to process it separately. (right-click the chunk, group save as into a different directory and folder structure).

Problem:

When trying to build an orthomosaic in the new project, I get the error:

Exception: Empty camera list


In the original project the same operation works fine.

All cameras are present and enabled (cam.enabled = True).

CRS is correctly assigned.

Question:

Is this a known issue when exporting chunks into a new project?

Could some camera references be lost during export?

What is the recommended way to export/import chunks without breaking the camera list?

Thanks in advance!

Hello Lukas,

What version of Metashape you are using?

Maybe you can also share to support@agisoft.com the following archives from the original project and re-saved project.files structure for the same chunk: chunk.zip and frame.zip?
