By putting a negative value in for time we can get a layer to trace out a portion of the path that occurs before time zero. Whatever time you specify, you get the wiggle() value that would occur at that time. This parameter works very much like the valueAtTime() method you can use to retrieve a property's value at any given time. We are able to access these negative time values of wiggle() by using the seldom-used fifth parameter of wiggle() - time. The blue dot is tracing out the portion that occurs between zero and positive three seconds. The red dot is tracing out the portion of the path that occurs between minus three seconds and zero. The trick is that the red dot is tracing out the three-second portion of the path that occurs before time zero. It turns out that the red and blue dots are actually tracing out the same random wiggle path. That seems like quite a coincidence, right? Well, there's a little trickery going on here that is key to making this all work. Notice that it starts near the right edge but ends up in the lower left corner - exactly where the blue dot starts. Now examine the path traced out by the red dot. It starts in the lower left corner and ends up near the middle of the right edge after three seconds. If you examine the lower movie to the right you'll see such a path traced out by the blue dot. Visualize a graph showing the path that our layer traces out as it moves randomly from time zero through three seconds. Not as easy as using an expression like the one you described though.Let's say we want to create a three-second loop of wiggle motion.

In mograph there are options for dynamics, same in mocca’s deformers, constraints, etc and you can code one in Xpresso. Seems like a pretty simple implementation to me.Īlthough you can do this with work arounds in each module. This would be a great feature to have imo, because one could easily animate overshoot in character animation, and animation in general. I’m a complete Xpresso noob.ĪFAIK there is not such a expression in c4d. Is there anything so easy and simple in C4D? I want to wiggle some values, like a Random Effector’s scale and position so my clones will gently hover and drift. It even works with keyframes, so wiggled values add/subject from the original keyframed value. I can easily connect sliders so I can animate the freq and amp too.

In AfterEffects, I can wiggle any property by simply typing the expression “Wiggle (frequency,amplitude)” and that it will wiggle around the initial value.
