The good old FumeFX Rocket Launch everybody probably did. : D
The main goal for me was to get the proper behavior of the sand getting dispersed. In this version it turned out a bit too thick and heavy in my opinion. Another goal was to improve my work with fast moving objects within Fume.
Fume Setup is made nearly entirely out of ParticleSrc emitters with some of the PFlow´s linked to the rockets. Another PFlow emitter blows out the dust and a second PFlow just emits Temperature for some more turbulence within. The only ObjSrc is creating a bit ambient dust near the ground. : )
