You should use the turbulence to add “low frequency” noise: rolling, churning, large-scale motion.įor each shaping parameter, there is a checkbox to turn the shaping type on, and a scaling factor to control how much of the shaping type to apply, and below those parameters are tabs containing control and visualization parameters for each shaping type.Įxpert users: The Pyro solver is implemented using the Smoke solver with additional subsolvers to provide Gas Sharpening, Confinement, Shredding, Turbulence, Dissipation, and Disturbance. I have tried everything to get this to be visible either in renders or even at the object level, cant seem to figure out any method to see it unless I'm inside the dop net. It squashes and stretches the velocity field to create the licks and flows typical of fire. I have a pyro solver inside of a dop net doing a very basic smoke simulation. Shredding is the main way to add “high frequency” noise to flames. With this toolkit you can create the smoke & reveal effect (which also got featured by SideFX Houdini) for any object. Houdini includes two different ways to add turbulent noise to fire: shredding and turbulence. However, the pyro solver is largely resolution independent, so you can often work in low resolution and then bump up the resolution with similar, more detailed results.
Remember that the resolution of the Smoke object determines how much detail you can get in the fire/smoke. All except dissipation affect the velocity field as internal forces. The parameters on this tab control the shape and development of the flame/smoke. Fast smoke simulation Houdini Hey, I was trying to get into smoke simulations with Houdini.
