This was an attempt at creating a volumetric looking smoke effect. It was totally improvised so it shows how I experiment to get the settings right.
After rendering the final clip I noticed I had to change the Particle>Size over Life curve so the particles size faded out rather than just disappearing abruptly. I also setup Aux>Opacity over Life so the auxiliary particles faded out (using opacity). Tutorial:

Starlings Study 02 from Peder Norrby on Vimeo.
Continuation of Starlings Study 01
This time I used the "Sprite" particle type with a 20x50 px comp as particle; a small triangle. I used Orient to Motion to make the triangles point in their direction of flight. The number of particles was set down to about 4K.
