Hi. I'm trying to make a test where bunch of particles fly up, and then freeze in mid-air, but I can't seem to get it right. I tried messing with the speed in the Lifetime Controls, but I can't get the stuff to freeze how I want them. For example in my Ground Crumble test, how would I get all the concrete to fly up, and then freeze all at the same time, at the exact frame I want them to freeze. Thanks!
