Need to Animate Edges (chainsaw)

[dkwroot]

Does anyone have any ideas regarding animating the outline shape of an object? For example, I would like the teeth of this blade to rotate around the blade.

Maybe a fast looping 3 frame cycle?

I know that FBF is a choice, I was just hoping someone had an easier method.

You can animate and cycle the curve profile to do this.

I was thinking the same thing. I originally tried to animate a curve profile, but kept getting sub-par results. Basically, as I animated the source curve, the main curve would have unwanted distortions. For example, the curve would wobble as it's source is distorted.

I decided to combine the idea of animating a curve profile with FBF. In order to do this, I made reference layers to the chain layer in a switch and gave each reference a slightly offset curve profile. It worked really well!

I used the same technique to create one of the Amoeba Boys from the Power Puff Girls.

This may be a bit simpler.

Can you get this to work for a waveform? When I tried, I get the distortion that I talked about earlier.

Waveform is the same idea, but probably won't look as smooth, especially the slower you run the cycle. In that case, your FBF method may be better.
