Particle : Rate controled by distance ? 2005-05-20 - By Guillaume Laforge

Fantastic !
Thanks for the tips :-) It works very well with the emitter animated along
a circle ( Particle clock look :-) )
Will be harder to use it in my scene (camera animation and interaction with
characters...) but I'll give it a try.
Thanks again Eric.
