Hi Ilia,

Thanks for the reply - you're correct about what I'm trying to do!

I've tried your first option and unfortunately the following dialog pops up:

"Unable to write file $FILE$ (file may be write protected)"

This dialog does not appear if the file is saved manually with the File -> Save Project As... Dialog

The save location is a network drive. Let me know if theres a workaround?

For your second option - is it possible to specify the exact filename here?

EDIT: It looks like you can also specify a filename here, which has worked - thanks !

C4D 2023

I am using the method in a custom script as follows:

c4d.documents.SaveProject(doc, c4d.SAVEPROJECT_SCENEFILE | 
c4d.SAVEPROJECT_ASSETS | 
c4d.SAVEPROJECT_USEDOCUMENTNAMEASFILENAME,
self.filedir,
            [],
            [],
        )

When using this to save an open project to a different directory, the newly saved project file (which remains open in C4D) locks up and the user can no longer save the open project with Ctrl+S or File>Save Project.

An error dialog pops up showing:

Unable to write file "FILENAME" (file may be write protected)

There are no additional errors in the Console.

Any ideas? This is a blocker on our current pipeline.

From what I can see

c4d.documents.SaveDocument()

Does not work as expected - saving the active document to the given filepath and keeping the active document open under that "new" name/filepath.

It saves the document to disk at the given path and you must then load that new document from scratch and kill the previous one?

c4d.documents.SaveDocument(filepath)
c4d.documents.LoadFile(filepath)
c4d.documents.KillDocument(doc) # close the previous doc

Is this correct?

If you have a heavy file and are saving to a network location with python, every 'save as' action means reloading the entire scene from disk, which can be pretty slow/inefficient?

Is there a better method?

Thanks
