Arnold - Windows - Batch render for student version

// HOW TO - RENDER A LIST OF SHOTS WITHOUT ARNOLD BATCH RENDER LICENSE

// 1ST STEP
// First, create a .bat which will look like this:
// Replace path to maya.exe with your own path, and with paths to your .mel files - How many lines as you want to render shots/scenes.




"C:\Program Files\Autodesk\Maya2018\bin\maya.exe" -script C:\YOUR_PATH\shot1.mel

"C:\Program Files\Autodesk\Maya2018\bin\maya.exe" -script C:\YOUR_PATH\shot2.mel

popd

pause




// 2ND STEP
// CREATE A .mel FILE FOR EACH SHOT/SCENE AS FOLLOWING




////////
//// PATH TO FILE YOU WANT TO RENDER
////////

file -f -o "C:\YOUR_PATH\your_scene_001.mb";

////////
//// NOTHING TO CHANGE HERE
