mayabatch

Easily batch process Maya files with any number of modules. mayabatch.actions subpackage comes with a template module.

Features:

Command line
python batch.py --help

Multiple Worker Processes through multibatch module

Cross-platform support (Haven't tested on Mac or Linux yet but it *should* work.)

Tested on systems with Maya 2012 and 2013

Extensible through actions modules

Command Line Single Process Example:

python batch.py --queue file01.ma file02.ma file03.ma file03.ma --modules mayabatch.actions.actionA mayabatch.actions.actionB

Python Multiprocessing Example:

import os
import mayabatch.multibatch as mb

if __name__ == '__main__':
    path = 'C:/Users/Administrator/Documents/maya/projects/default/'
    filepaths = []
    for root, subdirs, files in os.walk(path):
        for f in files:
            if os.path.splitext(f)[-1] in ['.ma', '.mb']:
                filepaths.append(os.path.join(root, f))
    modules = ['mayabatch.actions.actionA', 'mayabatch.actions.actionB']
    processes = 4
    mb.main(filepaths, processes, modules)

A simple benchmark produced the following results:

50 maya files
4 processes: 10.433 seconds
1 process: 8.145 seconds

350 maya files
4 processes: 15.353 seconds
1 processes: 26.932 seconds

As you can see it's a balancing act between the amount of processes and files. These tests were run on a system where maya's usersetup script is far from ideal for batch processing.

Notes

At the moment filepaths for each individual file are placed in the command line. Depending on the complexity of the paths the maximum length of args in a windows command prompt can be reached quickly. Pickling will be introduced into the mix to work around the command line args limit.
