I'm not sure you got my reply that I sent to you personally and I may be too
late here but send me your scene at mleclair(at)hybride.com and I'll see what I
can do. I'm sure it's a pretty simple solution but I need to take a look at
your scene and see how it's set up. Plus we'll be sure that the solution
will work in your scene and avoid me to try and reproduce what you are
doing. And don't worry about paying! It shouldn't take too long to fix
something like that!

Subject: Re: Particle event problem...
Hi Guys,
I'm still in a bit of a sticky situation here, I have around 500 fish so
I really don't want to be plotting them all and using up-vectors (right
now I've begrudgingly resigned myself to the fact that I have to)... and
I have to integrate these into a shot this evening...
Anyone? Please?.... Pretty Please?
I would even be willing to pay right now.... I'm serious.... What does
one hour of scripting cost around here? ;)
Cheers,
DAN
