Usually you’d find pyro setups behind all kinds of explosions, fires and sometimes fireworks, but how about something more calm? Something like a wind tunnel used to evaluate the aerodynamic properties of cars, trains and planes? (Please do not use this setup to evaluate any aerodynamic properties, it’s a visual setup, not necessarily a scientifically accurate one.)
In this tutorial we’ll go through the steps necessary to build a wind tunnel using Houdini’s pyro toolset. We’ll talk about emitting smoke, building a virtual fan to blow the somke over our test surface and setting up our simulation parameters.
