Automatically rig Cinema 4D splines with nulls for easier animation. Updated to Python 3 for C4D R23.
Copy the Python file to your Cinema 4D library/scripts folder, restart or open Cinema 4D.
Select a spline object, run the script! (In C4D R23 you can run scripts from the 'Extensions' > 'User Scripts' menu)
The script will create nulls to control each anchor point in your spline.
Modified BSD - available in the .py file
