I was working in a project with psd files and bones, everything normal. But in a scene a character should move from one pose to another and there was no way to make it only with psd. So I decided to use vectors, emulating the sketchy style.
I had problems with the hatched parts and this involved a lot of lines, making it a nightmare to animate them. Then I realized the noisy outlines could help.
The idea is simple, instead of drawing and animating 18 lines, I drew 3 and multiply them via noisy outlines (on vector layer proprieties). It worked fantastically and made the animation very easy, moving a couple lines you can move an entire hatched part.
The final result was very close to the original psd picture.
