The Channel Wrangle node in Houdini is a CHOP that let's you use VEX when working with channel data. In this video we create 3 channels, use VEX to fill them with data, and then "export" the channel data to geometry parameters.
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!
