Particle help - reversing animation of particles to original position

[stevesideas]

If I have a bunch of particles lock/bonded to a sphere and then an age test that releases them at a defined time, they then shoot off at a random direction and set speed. Is it possible to somehow bring the particles back to their original position after a specified time and then lock back onto the surfface of the sphere ??

There are a few ways to do this, but personally I'd use script operators to store & switch the position.

It's been a while since I've watched it but Allan McKay should cover most of the principles here : http://www.vfxsolution.com/allanmcka.../tut_ObjAB.avi

Thanks for that. I'll check it out
