I have created a "directional emitter" and made "a spread value of .2" and to that particle i have attached gravity.
And i have written an expression for the radiusPP to emit random radius "spheres" and now what i want it is,
the emitted spheres travels to small distance in ydirection and falls, while falling i want the larger spheres to fall faster and the
smaller spheres to fall slower.
If any body knows, kindly post your reply.
