The creators of some of the Best Adobe After Effects plug-ins have updated their powerful 3D particle system known to the motion graphics world as Particular. New features to the plug-in are Depth of Field, Motion Path, and Particle Count.
Check out what this means for you:

Depth of Field: is useful to generally increase realism or to match footage shot with a real camera where Depth of Field is apparent.

Motion Path: is useful when precise control of the particle path is needed.

Particle count: is useful when trying to optimize a render, always try to keep both numbers as low a possible.
