VideoFort Don shows us how to make a group of spheres explode, slow down, then return to speed.
Start out by setting a floor and sphere in a new project, from there you clone the sphere into a grid and put a random effector on it to make it less uniform. Your plane and cloner layers need to be set to rigid body and the cloner’s individual elements need to be set to all, this will allow the spheres to move freely instead of as a group. VideoFort Don then shows us where and how to set keyframes using timescale to create the slow down and speed up motion.
