Nick Medukha shows how you can set up a system for advecting particles in Houdini.
A new tutorial covering working with particles in Side FX Houdini by Nick Medukha shows the foundation for creating particle advection. The tutorial covers emitting and driving particles with a Pyro simulation in Houdini using smoke to move particles organically and naturally.
Medukha’s tutorial looks at the relatively common technique of advecting particles by pyro smoke. The tutorial also runs through using collision geometry and how to fill an object with particles. You can download the project files here to follow along.
