Shaking contours effect

I want to make an effect with shaking contours. How to do this in Toon Boom Harmony? Like in this After Effects tutorial: Hand Drawn Effect in After Effects - Tootorials - YouTube
Also in Anime Studio this effect is called ‘Animated Noise’.

It is also known as “boiling” but I don’t think there is a simple node effect to produce it in Harmony.

I found this thread after a quick search. You might be able to come up with more:

An example, “The boiling contour lines are achieved by cycling multiple pencil textures.

Toon Boom Rigging: Morph Rig Demo on Vimeo (cannot embed Vimeo videos here)

Here is another example of the effect produced in Harmony but I have no idea what method was used to achieve it. Just posting it here to show that it can be done:

i think the vimeo example above is purely hand drawn frames (with some reused drawings looped into cycles), not a post effect at all.

one post effect idea, if harmony premium, consider network surgery – isolating the linework (or whatever sublayers you want) and passing that isolation into, say, an OFX plugin that’d randomly excite the target sublayers.

might be some cool tricks in h15 with the texture lines, too. (interpolate parameters over time, or cycle styles)

I quoted the animator’s description for that Vimeo example.

Here is another example and approach:

“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”

sorry, meant the youtube clip (below the vimeo).

“cycling textures” might be another way of saying three different drawings? It’s common on hand-drawn indie/arthouse work to trace a drawing three times for the shaky lines aesthetic. 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.

thats a great result!
Question: What does the matte look like for your test? I’ve been messing around with the node set up you’ve posted for a while now but I can’t seem to understand fully the matte aspect; Are you manipulating the matte to achieve the final look for the lines?

If so, could you share the set up you have for the matte as well?


I used the lines you see on the image on the left as the matte. Those lines, via the refract effect affect the artwork. In the example, they affect only the line not the colour, which I separated using Line and Colour-Art modules. For the refract effect to work properly, the matte needs to have some some of movement. In the case I made it go up and/or down with a peg. You can try a more random movement, slower or faster, etc. Instead of using a peg, you can use something traditionally animated, for instance circles growing outward for a water ripple effect.
