Objects are still not displayed after ChangeNBit is works

[gheyret]

Hi Everyone!

I'm Trying to use GeListNode.ChangeNBit(c4d.NBIT_EHIDE, c4d.NBITCONTROL_SET) to hide some objects and save the project file and close it.
And I open the project file again and try to using GeListNode.ChangeNBit(c4d.NBIT_EHIDE, c4d.NBITCONTROL_CLEAR), I find that although the code works, but the hidden objects are still not displayed in viewport.

Is this a bug or something special thing happend?

This is the project file I tested, and it's already hide the 4 objects top of the OM:
show-hide_test.c4d

And this the simple testing code for displayed them:

import c4d

doc: c4d.documents.BaseDocument  # The currently active document.
op: c4d.BaseObject | None  # The primary selected object in `doc`. Can be `None`.

def main() -> None:
    objs = doc.GetObjects()
    for obj in objs:
        if obj.GetNBit(c4d.NBIT_EHIDE):
            print(obj.ChangeNBit(c4d.NBIT_EHIDE, c4d.NBITCONTROL_CLEAR))
            print(obj.GetNBit(c4d.NBIT_EHIDE))

    c4d.EventAdd()

if __name__ == '__main__':
    main()

---

P.S: I also found that after running the test code in the above project file and saving the project, closing it and then opening it again, those hidden objects came back.

Hi, thanks a lot for the report, I filled a bug report.

As a workaround you can enable and disable the deform mode and it will work.

import c4d

doc: c4d.documents.BaseDocument  # The currently active document.
op: c4d.BaseObject | None  # The primary selected object in `doc`. Can be `None`.

def main() -> None:
    objs = doc.GetObjects()
    for obj in objs:
        if obj.GetNBit(c4d.NBIT_EHIDE):
            print(obj.ChangeNBit(c4d.NBIT_EHIDE, c4d.NBITCONTROL_CLEAR))
            print(obj.GetNBit(c4d.NBIT_EHIDE))
            if obj.GetDeformMode():
                obj.SetDeformMode(False)
                obj.SetDeformMode(True)

    c4d.EventAdd()

if __name__ == '__main__':
    main()

Cheers,
Maxime.
