XSI, Pyroclastic smoke, Particles

quick example of a volcanic pyroclastic cloud done with the default particle volume shader presets and a basic emission. Really just modified one of the example Softimage scenes to fit in order to demonstrate how far you can get with just particles for this effect. Obviously not as realistic as a proper fluid simulation but a heck of a lot easier to setup in Softimage so far here is the scene to download from my Google drive
