How to create a Spraying Effect I am making  drone animation which includes the drone spraying pesticide on plants so how do i make the spray effect as in spraying a fluid on the plants. Thank You
My instinct is that you either want a particle simulation (for droplets) or a smoke simulation (for a fog).

Neither of these is trivial to pull off.  I can imagine that getting the "smoke" to flow down will require some tweaks.
