This question already has an answer here:

I am trying to achieve a deliberate line boil effect in a pose-by-pose animation. Similar, for example, to the effect achieved in Dr Katz (I know this particular example was done with software rather than by hand).

My process is currently:

  • hand draw a pose
  • trace second version of pose (with some deliberate tracing badness to achieve line boil)
  • scan both poses
  • repeat for new pose
  • for each pose, display for desired period, looping through two versions

However, the effect is not as I intended. There is often an illusion of movement, rather than a mostly-still pose with vibrant lines, and my intuitions about which lines to boil, and how to boil them, is sometimes just plain wrong. How can I instead achieve an effective line boil? (For example, do I need more than two boiled versions per frame? If so, how many? What line variations generally work, and are there any in particular to avoid? Should I avoid any simulated movement, including gestures and mouth movement?)

(The software I am using happens to be GIMP + Inkscape, but this is mostly for aligning / tweaking images, not the actual drawing or animation. I believe the answer lies in what I'm drawing rather than software, but I'm tentatively open to software related advice.)

This question was marked as an exact duplicate of an existing question.

From my understanding, GIMP and Inkscape are primarily image and vectore manipulation tools. I think that you need to look at filters that add an extra layer of rendering to your work - have you by seen sketch and toon by cinema4d? they have a line randomness settings that adds that slighlt layer of imperfection to the renderings.
