Houdini 20.0 Shelf tools

Volcano shelf tool

Creates a voluminous column of thick smoke, as from the rim of an erupting volcano.

Overview

Creates a voluminous column of thick smoke, as from the rim of an erupting volcano. The resolution (Divisions) of the cloud’s pyro box is low to begin with. As you play with the parameters and start to get the motion you want, increase the Divisions to get more detail.

On the Pyro solver node

  • Use the Smoke amount to control the amount of secondary smoke.

  • Use the Heat output parameter to make the plume rise faster.

  • Use the Gas released parameter to influence the size of the plume.

  • Use the Shredding controls to rip the streaks apart.

  • Use the Disturbance and Turbulence controls to add detail or change motion.

See how to use the pyro tools.

Tips

  • If the object has a velocity point attribute (v), the Volume Rasterize Attributes SOP will create a velocity volume for the simulation.

    To add velocity attributes to the object, use the Point Velocity SOP.

  • Use the disturbance and turbulence controls on the Pyro Solver’s Shape tab to add detail or change motion.

  • Use the settings on the object’s Pyro Source and Attribute Noise SOPs to change the emission.
