Particle Shockwave

The Particle Shockwave effect I did for short film: Plank. The director of the animation short required a Super Saiyan Energy effect and a shockwave.

I did the particle simulation in Houdini, I first used pyro simulation to get a general motion, and then use advect by volume node to drive the particles according to the velocity field from Pyro Sim. For the shockwave effect, I used small particle simulation generate a shockwave of particles, then I used them as the source of smoke and velocity for the smoke sim. Finally I generated roughly 70 million particles using the PRT exporter( which serves the same purpose as WEDGE to output multiple version of cache) to export the particles to render in Krakatoa.
