Maya to deadline job submission python command

I am trying to send maya renders to render farm by Deadline Software.

Python Command for Manual Job Submission Maya to deadline.



import sys
import subprocess
import maya.cmds as cmds

deadline = "C:\\Program Files\\Thinkbox\\Deadline\\bin\\deadlinecommand.exe"
maya_exe = "C:\\Program Files\\Autodesk\\Maya2015\\bin\\render.exe"

file_path = cmds.file(q=True, location=True)

command = '%s ' \
'-SubmitCommandLineJob ' \
'-executable "%s" ' \
'-name "File Name" ' \
'"%s" ' % (deadline, maya_exe, file_path)
process = subprocess.Popen(command, stdout=subprocess.PIPE)
lines_iterator = iter(process.stdout.readline, b"")
for line in lines_iterator:
print(line)
sys.stdout.flush()


any python ways to add maya renders to deadline..?

Answer

Finally, I got the way to send maya render jobs to deadline render farm software. all we need to do is write 2 job files for deadline. 1. maya_deadline_job.job 2. maya_deadline_info.job

and pass these files as arguments in deadlinecommand.exe for example:

deadlinecommand.exe "maya_deadline_info.job"  "maya_deadline_info.job"

Here is my python code
