This script imports a Cinema 4D scenefile and disables all deformers, generators and expressions. This is useful if the scene was saved at a state it is unrecoverable because of an issue while scripting (eg. saved the scene before a Python tag was executed, but now that Python tag always runs in an # infinite loop).
