Houdini Pyro Tutorial: Implosions and Smoke Suction

Quick walk-through of how smoke suction and implosion effects are achieved in Houdini using the pyro solver. I would encourage to experiment with this in your own smoke simulations and try to adjust the size, location, or the strength of the divergence and sink volumes. You can also achieve some cool effects by animating the divergence source scale between positive and negative values. Another idea would be to have several divergence sources scattered around. Hope you enjoy this technique and find it useful. 0:00 Intro 0:03 Density Source Overview 1:18 Smoke Suction 3:24 Animating Suction Scale 4:12 Smoke Sink
