hello,menno
i followed to experience custommeshobject with python. however, encounter a problem with error message ‘need public constractor’. can u help to take a look slight_smile:

Creating a custom mesh object in Python is probably not possible hard to maintain due to the dynamic nature of Python.

Why do you need a custom mesh object? What problem does having a custom mesh object solve?
