• Running list of cmd.exe commands from maya in Python

  17 décembre 2015, par user3541686

  I am writing a maya python script to batch render a scene into jpgs then use ffmpeg to turn them into a mov. Currently the script saves a string of commands as a bat file which works fine but I’d prefer to just run cmd.exe from maya and execute the list of commands without creating that bat first.

  I’ve been reading about "subprocess.popen()" but I can’t figure out how to get it to iterate through each line, run that command, then move onto the next one when done ie :

  1) Run maya render.exe & save scene as jpegs

  2) ffmpeg jpgs to mov

  I’ve shortened the directories but its essentially this :

  `C:\PROGRA~1\Autodesk\Maya2015\bin\Render.exe -r hw2 -s 100 -e 200 -of jpg -fnc 7 -x 1920 -y 1080 -rd 
  
  "C:\RENDER" 
  
  "C:\SCENE.ma" ffmpeg -y -r 25 -start_number 0100 -i C:\SCENE_%%04d.jpg C:\SCENE.mov

  How would I be able to do this ?

  Thanks !
