    I have a question, related with the physics, in trapcode particular wich is:

    Can i customize a shape to do what the spherical field does (physics>Air>Spherical Field)? My objective is to create a custom shapes (or bitmaps too), so that the particles emited dont go to certain parts of my comp. Is this possible?

    Thank you very much.

    Nope.

    You might be able to cheat this some by making use of Bounce mode with a floor and a wall, but you sadly cannot define arbitrary shapes for attraction/repulsion.

    An effect like this would be more easily done in a proper 3D app’s particle system.
