Export an entire scene collection to Mashleb


I would like to simplify a car body with the help of MashLeb.

Meshlab has like Blender the function “Decimate”, but can do it better.

Therefore I would like to export a scene collection to MashLeb. Unfortunately only a part of my scene collection is exported to MashLeb.


How can I export the entire “Collection1” to MashLab in one?

Thank you very much for your help!
