There are many parts of CG pipeline that can be automated and made simpler by writing code. Modern rigging for instance does not rely on hand-making rig parts for each character.

Many companies have Pipeline TD or Engineering departments responsible for automating the daily tasks of artists. And of course programming skills can be very beneficial for artists themselves.

After taking this class an animator, modeler or a rigger will learn how to make their process faster and easier through writing code that will take care of the tedious parts of their work.
