Dude thats way more close than I ever got. Thanks so much. I didnt even think of building like that. I was getting kind of close using the StepEffector to apply weight to the tube clones and then using a plain effector to expand them out. I made two tubes one big one small and then blended them with a cloner. However, same problem – the animation is not as smooth or organic and the expansion is not always in the correct order. The animation in the video was built using Maya. Im just surprised its so hard to replicate that radio wave effect so popular in after effects, in c4d. I thought something like this would be plain and simple, I thought wrong.
