I've been hunting around for a couple of days for a solution to this but can't seem to find anything to help with the last half of the sequence.
Basically it's a glorified transition shot. There is a product on screen with text and images which explodes into particles. That bit is easy, tons of tutorials on that. The next bit is I want those particles to slow to a stop in mid air and then get sucked all very fast to a single point as if I just opened up a black hole there and gravity has ripped all the particles out of the scene.
So explode is covered, any methods to stop the particles and them attract them all to a single point where they die off?
