There=92s more than one way to do it, but something like this should= =20 work:

I'm=20 working on a project that requires a Base comp be built that all the artist= s can=20 use.=20
it's a Trapcode particular effect that needs to add to amount for = particles=20 emitted depending apon
velocity of the emitter ( using a null to drive the emitter)
i.e. moving slower less particles, faster more particles.
=A0
any suggestions ?
=A0
Thanks
