Popcorn FX fractalFlame
Popcorn FX is capable of some pretty sophisticated particle effects. With a little effort one can get past the “usual” turbularized effects and push the limits a bit. Here’s a “fractal flame” look made by spawning, coloring and moving particles with layered noise fields. Given the number of particles used to give the soft look it’s not really something you could include in a game or application but was a fun way to explore some techniques which could be used for more efficient effects. You can get a similar look with much better performance using a vertex shader to distort a mesh and a fragment shader with an additive fresnel transparency, but again the point of the exercise was more an exploration of PopcornFX. That said, this does run in realtime with about 24 fps in the editor, pretty nice.
