cmiVFX has released Modular Rigging with Python in Autodesk Softimage; an in-depth course in which our mentor, Jérémie Passerin, takes you through the whole process of creating a complete modular rigging system in Python.

The two first chapters will get you comfortable with the basics of programming with Python and using the Softimage SDK. The video gets more advanced from there as Jérémie explains in detail how to create all the different components of a biped rig. You will learn how to get information from the scene and create new objects, apply constraints, use expressions, and connect everything together by using Python scripting. You will even see how to create a custom operator and use it to create a stretchable IK solver. For those who are familiar with the open source rigging system GEAR, this video will give you the basics you need to understand the core of the system and make it possible to extend it.

Chapter Descriptions:

Most browsers cant play 11 hours of video without losing audio sync, so this video is downlod only. You can try to watch the online version, but the files are small enough to download quick.
- Python Basics
Learn the basics of Python programming, the different datatypes, statements and how to control your workflow. Learn how to create your own functions with arguments. Understand Classes and Inheritance. Discover how to access objects and manipulate data in Softimage.
- Python in Softimage
Create your own Python library to store all your python code and learn how to use it from Softimage easily. Learn how to manipulate and reuse your code. Create your first tool; a simple Search and Replace to rename objects in the scene. Finish by learning how to create a curve and attach it to object.
- Creating the guide and the initial hierarchy
Start working on the rigging system. Learn how to organize your work in models and create the initial hierarchy that is used as a guide to build the rig. Write your first python class to control this guide.
- First Component - Single controller
Learn how to create your first rig component. This very simple controller is the base of any rig. You will learn how to use the inheritance of a class to create your own custom component.
- FK Chain
By creating a simple FK Chain, you will learn how to use the power of inheritance to reuse most of your code from the first component. You will also learn how to calculate the transformation of an object in space to create your FK Chain properly.
- Spine
In this chapter we are moving forward with a more advanced component: the Spine. Create the controllers, the curve, and the deformers twisting properly along the path.
- Connect the components together
Define connections and slots to create a very flexible rigging system; allowing you to create any kind of character.
- Custom IK/FK Solver
A quick infidelity to Python to have a look how to create custom solvers in javascript inside Softimage. This chapter will help you understand how custom operators work and what they can be used for. This example will get you through the algorithm of a simple but robust IK Solver with native stretch.
Here we return back to Python. Use your custom solver to create your arm component.
- Leg and Foot
Adapt your code from the arm to create a leg component and add the foot rig with properly reversed controllers, allowing the animator to create a walk cycle easily.
- Fingers, Neck, and Symmetry
Use your FK Chain component to add the final touch to your biped rig. Symmetrize all the components to create a full body. You have now created a flexible and extendable rigging system ready to use on your characters.
