Welcome. In this series, we'll use Houdini 16 to create a rising flare coming off an airplane. Mainly, we’ll concentrate on the pyro effect. We’ll also deeply cover Houdini clustering, which will help us a lot, especially in this scene. First, we’ll bring our airplane model in, we’ll animate quickly, we’ll create and apply our source, and then, finally, we’ll create our beautiful pyro effect. Before you start, do some quick research and R&D and gain a clear idea of what you want to create, so that as you follow along your final effect will be your own creation. Take what you learn here and build onto it, and take off!
