Rename object by filename

Jasper Sek

Hi there! Do someone know a way to rename a nullobject in c4d by the filename, so that the name of the null-object changes, if the c4d-file changes? I mean something like the token-system at the renderpath.
I never used python before, just a bit of xpresso. That would save me and maybe others a lot of time.

You just need to add a python tag to your object and paste the following code.

Simple as that:

import c4d

def main():
    if not doc:
        return
    doc_name = doc.GetDocumentName()

    null = op.GetMain()
    if not null:
        return

    null.SetName(doc_name)

Download here: null-docname.c4d

Hope it helps.

Cheers,
Lasse

Wow, Thanks a lot!

@lasselauch What if i just want the name without .c4d?

@lasselauch sorry i'm too bad at this. cant fix that. i found this before, but i don't know how to implement it in c4d.

Of course there are a lot of ways to spin this, but I guess in most cases this should be enough:

# import os
import c4d

def main():
    if not doc:
        return
    docname = doc.GetDocumentName()

    # docname, _ = os.path.splitext(docname)
    docname = docname.replace('.c4d', '')
    
    null = op.GetMain()
    if not null:
        return

    null.SetName(docname)

Hi @Jasper-Sek,

thank you for reaching out to us. And thank you @lasselauch for jumping in. The solutions provided by @lasselauch are correct, but one might want to consider that Cinema is also capable of opening non-c4d files (I know, it's crazy ;)). So you should use os.path.splitext(docname).

PS: @lasselauch I know that you meant this in a light-hearted manner, but "let-me-google-that-for-you" can be misconstrued. People have different information needs and things that seem trivial or obvious to you, are not for them. Programming can be a confusing topic and we would like this to be a welcoming place for everyone and subsequently stay away from all "RTFM"-notions.

Yep, definitely meant in a light-hearted manner!!!
You're totally right.. that's why I provided the correct answer.
