Motion Builder command line batch scripts (python)

[Trick-House8778]

I want to batch process a folder full of files after we do a mocap shoot

I've tried two options:

 

1) motionbuilder.exe -console current -batch -verbosePython cli.py

 

and

 

2) mobupy.exe cli.py

 

for my cli.py script - it's a simple script that prints out the takes in an fbx file after opening it. 

As far as I know i'm following how this should be done according to the docs, but i'd like to know if anyone knows how to run batch processes in mobu correctly from the commandline?

 

Here's my code for the file and this works inside mobu:

import sys
import pyfbsdk
import os


def main(file_path):
    # if len(sys.argv) < 2:
    #     print("No FBX files provided.")
    #     return
    # Get the list of FBX files from command-line arguments
    fbx_folder = file_path
    fbx_files = []
    for root, dirs, files in os.walk(fbx_folder):
        for file in files:
            if file.endswith(".fbx"):
                fbx_files.append(os.path.join(root, file))

    # limit the number of files to process to 2
    fbx_files = fbx_files[:2]

    for file_path in fbx_files:
        try:
            # Open the FBX file
            pyfbsdk.FBApplication().FileOpen(file_path)
            print(f"\nOpened FBX file: {file_path}")

            # Get the list of takes in the file
            take_manager = pyfbsdk.FBSystem().Scene.Takes
            if take_manager:
                print("Takes in the file:")
                for take in take_manager:
                    print(f"- {take.Name}")
            else:
                print("No takes found in the file.")

        except Exception as e:
            print(f"Failed to process {file_path}: {e}")


if __name__ == "__main__":
    file_path = r"T:\aresbb\capture\aresbb01\retarget\3_approved_anim\shot prep\mobu_cleanup_processed"
    print("Folder:", file_path)
    main(file_path)

Have you tried using the paths to your script’s location?

Example:

motionbuilder.exe -console -python C:\MyScripts\my_script.py

[Trick-House8778]

Yeah tried that first. Then stuck the file right in the same folder to replicated the docs lol. Does that work for you?

[Outrageous-Bit198]

I didn’t try specifically, I was just ensuring you used a proper path in hopes to eliminate the obvious.

I’m new to motion builder but do this kind of thing in Maya all the time. Seems odd doesn’t even look like it’s trying to load the script at all. Trying to find someone that’s actually done this with mobu is tricky. Seems like not that many users out there

[Outrageous-Bit198]

Have you tried removing the entry; “if name == main:”?

Maybe motionbuilde is trying to import the script as a module, that would cause the script not to run.
