if you need some effects for your still images like smoke and dont want to use your particle effect system in your renderer you can have this maps for free and save rendertime i made the color maps© and the alpha maps(a).i made this effects in particle illusion,i modified some existing emitters.grab it if you like it and if you want more i try to make for you some effects(free for ZBC).
