if its at all usefull for you:
you can select the particles (select the cloud, go to tag point mode, tag
the particles) and plot their curves.
no messing about with attaching objects to particles, which is way to slow
to be fun.
Mind that when they die, and new particles are generated, the particle ID
gets recycled so this messes up the plotted curves! So this works best with
clouds that generate loads of particles in the beginning and then stop
generating.
You can then with a simple "for i = 1 to x" loop path-constrain objects to
the curves with tangency and all.
And by using the point count of the curve, you know how many frames are
needed to animate from 0 to 100% on the curve, and you can script placing
those keyframes...
(havent got the script I made once for this at hand, but it was very simple
in the end)
- the cloud has to
