I'm about to model a piece of cheese, and I would like to give it some kind of smell effect as it's known from cartoons when a cheese is too old, or if someone with smelly feet takes off the shoes... Well, guess you know what I mean...
Now I want to make that kind of effect in blender. Of cause, it's going to be in 3D, and I hope it's possible to make it look a little more realistic than the cartoons. Also, I would like the "stink" to be half green, half transparent so that it is visible, and you know exactly what it is, but still not so green, that it looks more unrealistic than it's necessary.
I only need this effect for pictures, so it doesn't need to have an animation effect to it.
