The particle simulation was created using Exocortex Slipstream and rendered with Fury.
Slipstream system that I created randomises emit rate,speed,particle age and particle alpha to add variation. It also spawns a vortex fan from the emitter.
First time rendering with Fury, this had some motion blur and depth of field applied.
If anyone is interested in this system, please comment and I will be more than happy to package it into a compound and upload it.
