FBX does not export

[pyxelrigger]

Im developing a simple script to export an .FBX just the "Joints" object of each .c4d file in a folder, it works without any errors on console but it doesn't create any .FBX file in the folder I define

import c4d
import os

    #print (plugin)

    data = {}
    plugin.Message(c4d.MSG_RETRIEVEPRIVATEDATA, data)

    c4dfileslist = os.listdir(c4dfilesfolder)


    exportpath = c4d.storage.LoadDialog(c4d.FILESELECTTYPE_ANYTHING, 'Save .FBX Files', c4d.FILESELECT_DIRECTORY, '','', '')

Hey @pyxelrigger,

Thank you for reaching out to us. It is always difficult for me in these cases to find the right words. Generally speaking, what you ask us to do here, is out of scope of support: Either debug your code or finish the script for you.

What I see here is primarily a user who is overwhelmed by his or her own code. Especially when you are less experienced: Just break up things into manageable pieces where you know what they do and you can confirm that they do what you mean them to do. And when I run into troubles, the first thing I would also remove is all UI fluff. You could for example define your paths just at the top of the script. Finally, NEVER do this c4dpath = '{}\{}'.format(c4dfilesfolder, file), this is just bound to go wrong. Use os.path.join instead.

You will have to debug your script yourself.

Cheers,
Ferdinand
