I was trying to make the question more “general” about adding randomness to any VF/Dynamic variable. Specifically, what I have is an object that is fractured with all pieces static. I then want to move the object and have each fractured piece respond differently to that movement. i.e. some follow faster and some follow slower. I want to add some variability to the amount of drag, if that makes sense. I’m getting close to what I want via the “follow position”, “drag” and “lift” variables, but I’d still like to know how to feed an initial random number into any VF or dynamic parameter.
