Simon Verstraete shows how to model and simulate a flag on a flagpole in Side FX Houdini.

A new tutorial from Simon Houdini (Simon Verstraete) shows how you can make a procedural flagpole and flag in Houdini and simulate the flag waving in the wind.

The first part of the tutorial focuses on creating the geometry to create a simulation later. 

The tutorial also covers creating a base setup for the flag so that it is easy to tweak the size, for example. You can quickly get to that node and play around with the values.
