problem with initial particle directions with dupliverts

in the following image:

I am trying to get the rings at the back of the CD to have an iinitial direction away from the CD and not to have the doubling up as you are seeing here.

my question is how do you change the initial direction?
I have tried:
Rotating the dupliveterted object aroundChanging the positivity of the particle force
The animation is OK as is, but knowing how to control this would make other WIPs better as well as improve this one.

Crank up the Key parameter of the particles system.


thanks it worked :slight_smile:
