In Houdini you can control parameters using the HOU Python module. In this video we give a quick over of the HOU module, and show you how to use Python to change parameter values, expressions, and keyframes.
With our Houdini series we'll take an exploratory approach. Playing around with all the different nodes, and trying to build interesting & challenging models and simulations. Houdini can be intimidating at first, but with a little bit of experimentation, the complexity starts to dissolve and a powerful and simple tool emerges. I hope you will learn to love Houdini as much as we do!
