My first attempt to create magical and non-natural phenomena type of FX with Houdini.
I was simply inspired by this video vimeo.com/29990537
And my goal was to build up fully procedural particle setup to generate black holeish look with some particles. Setup contains pretty simple and basic velocity control system made by VOPPOP. The basic idea to achieve this FX is pretty much the same idea commonly used for Tornado type of FX.
Hope you enjoy this video.
