I've been forcing myself to use Houdini instead of Fume.  So here's my go at some pyro fire.I gotta say Houdini is a beast.  It is the stuff of dreams and nightmares combined.   It is basically limitless to how far one can go to achieve a desired look and feel.  If you have ever wanted absolute control or wanted to break things down to each and every component(and components inside of those components)  Houdini is your app. I feel like I'm just scratching the surface after weeks making fire and smoke.
