Animating squiggly lines with Toon Boom Harmony?

Hello, I wanted to see if I could animate some squiggly lines, like those seen in Dr. Katz.

I know how to do it in After Effects, but being able to do it on a per-character basis would be much more useful.
Is there a node I can use for that? I can’t find anything that helps.

After some looking I found this, but I can’t find that Line FX which was used:

How to do it?

  1. The best thing is tomake new drawings and loop them.

If you use vector drawings I guess best way is to duplicate first drawing and then adjust them a bit.

  1. You can put an evelope deformer to it too and loop these keys.

  2. There is some wave nodes but they not make a good job in this case.

I’m looking for an automated way of doing it, an alternative to how After Effects can do it with just a preset and a few parameters.

This might be useful. Starts at 5:58:
( in case the video does not show up: https://youtu.be/MCtbL5iPHoc?t=358 )

You have to do that frame by frame and the result is not what I’m looking for.

This is exactly what I need:

But I can’t find this Line FX anywhere.

Maybe it’s made with a script.

The result looks pretty close to me.

The lines don’t move, only the texture inside them.
The video I posted shows that the effect I was looking for is possible to apply automatically in Toon Boom Harmony without having to copy and paste different frames through the whole scene, maybe a developer knows how it was done?

Well, I don’t know… Maybe somebody knows how it was done?

Regarding the 2nd example Andy Powell’s, I played the video slow motion it is line texture movement not line movement.

Have a better look at it and look at the intersections move around. Andy Powell’s Line FX is clearly deforming the lines, not just changing the texture.
And that’s exactly what I’m looking for.

Looking carefully at the left figure’s intersections comparing the two there is no additional line movement between the two if you take into account the texture shifting.

This question popped up before on the forum, in this thread: https://forums.toonboom.com/harmony/general-discussion/shaking-contours-effect
The same example (No line FX vs Line FX) was given.

Back then, I tried quickly something similar with the Refract node (comment #6).

Quoting myself:

I think the other example (the No Line/Line FX) could be achieved via a number of options including a Refract module or Turbulence.

Here’s a quick test using the Refract node:

Here’s the Nodes used for the effect:

It can be tweaked with the shape of the matte, the speed it moves or shakes and the values on the Refract module.

I cannot remember a week ago it seems. At least it can be determined Andy Powell used more than one effect module type to achieve that result.

“Here’s an example of the new loose traceback line FX I’ve come up with in Toon Boom Harmony. The example is the raw animation, verses the line FX. It uses the raw line data and passes it through some effects modules. Useful for automating the entire process of re-creating the arty boiling linework of independent films”

If Andy Deffen cannot figure out the exact approach Andy Powell used he should be able to find his own way to something similar while experimenting with the suggested ideas. He will have that experience under his belt…actual hands-on experience instead of something handed to you is always good and not a waste of time and effort. But I can certainly appreciate the benefit of not having to reinvent the wheel.

Best of luck Andy.

Happy exploring and experimenting.

That looks more like what I was looking for, thank you. I’ll check it out and see if I can adapt it to my needs, since it seems a bit too fast in the example.

Just saw that a similar effect to what I’m looking for has been used in the new Toon Boom Harmony demo:

Has this effect finally been added to Toon Boom Harmony 17 as a node?

Hello Andy!

I’ve talked to one of our awesome training team members and they provided me with something that may help you out:

"Here are two examples.
https://fileshare.toonboom.com/wl/?id=lX07vfmZHBXAAaEVtxLi4mNPMuqLnxiJ

The first one of them is using a turbulence effect. You can easily affect the amount of turbulence applied to the line and this can also vary through time. You will only be able to see the result in render preview mode.

The second method is using a pencil texture and colour-override node. I am also using a peg to offset the texture randomly to give it a more hand drawn feel.

They both give different results, so pick the one you like best. : )"

Let me know if this helps!

Hey, the first example looks like what’s seen in the demo! Thank you!

Quoting dstruble:

Whether it helps the OP specifically or not, this is the level of response that helps Toon Boom Harmony shine. Not only does it show what can be done, it shows how it can be done, it shows TB is receptive and interested in the research and construction of solutions addressing user needs.

Thank you and good job!
