Maybe that explanation will give you something to build on. I found Dan's smoothing function: temp thisComp.layer ('Null 11'). (1) temp 0, temp 1 But it only make my streaks smaller, not smoother. However, the resulting wiggle is pretty jaggy. For example, if the time between keyframes is one second, then the layer rotates from 0º to 90º, but if the time between keyframes is two seconds, the layer rotates between 0º and 180º. Hey all I am wiggling a Null position as an emitter for Particular. To create an expression that does exactly what you want it to do would require you to give us the exact parameters. If you wanted the time between keyframes to generate a minimum and maximum angle. REnd = ease(t, tMiddle, tEnd, maxAngle, restAngle) ![]() RStart = ease(t, tStart, tMiddle, restAngle, maxAngle) The Wiggle Expression in After Effects (or AE Wiggle) is a great way to make objects move randomly, have some sort of idle Movement in character joints, animate a random camera shake, create wobbly text or animate a flickering light. ![]() Let's say that if the time between keyframes is greater than 1 second, the layer does not rotate, but if the time is less than one second, the layer would rotate 180º and back again. If you want to use the position of a keyframe in the timeline to control the rotation of a layer, use two ease or linear interpolation method and the time between the keyframes and then set the ratio between the two times and the maximum angle.
