fix to prevent script nodes from executing automatically in autodesk Maya

userSetup.py

# !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

# PLEASE READ!

# put this script in this directory (OR add it to your userSetup.py file. this code MUST be in userSetup.py to work):
# "%USERPROFILE%\Documents\maya\####\scripts"
# or
# "~/maya/####/scripts"

# this script creates a maya "callback" that executes every time ANY file is created/loaded/referenced in maya.
# The "callback" kills all <SCRIPT NODES>, making sure the scene is SAFE for users
# >>> Autodesk Maya Scanner tool does NOT clean <SCRIPT NODES> in references <<<

# !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
