I just got after effects and Ive been toying with it, but Im finding it a little less then intitive, which is typical of adobe. But heres my problem, Im sure youve all seen the Sin City(at least anyone in the US) and in the trailer theres a scene with one of the characters (Marv) against a black background and theres this white rain falling all around him. And I know after effects can create this effect, and I think Im on the right track with the particle system, but can anyone help me out? or at the least point me in the right direction? Im pretty new to any kind of compositing in general.
