Smoke Machine emits procedural smoke from a point, with plenty of options to make it your own.
Apply it to a shape layer, then adjust the settings in Effect Controls. For more smoke particles, open the shape layer and, in Contents, MoM Smoke Machine, Smoke Particles, duplicate the Smoke layer as many times as you like.
To install, drop the .ffx into your After Effects User Presets folder under Shapes, refresh the Effects and Presets list, and it appears under Animation Presets, User Presets, Shapes.
