I'm using the Hatch Shader to simulate a sketched drawing look and have simplified the scene for the sake of this post.
Any suggestions on how to achieve a subtly buzzing/moving line similar to if the images were drawn in stop motion (and redrawn every frame)? I'm not looking for anything extreme or complete redraws so it may be a trick like an expresion to shift line offset every frame. (or hopefully simpler)
My problems with the current animation is that it just appears to be an overlayed texture and has no life/animation.
An extreme reference to what i'm looking to accomplish is this:
The easiest way to do it, IMO, would be to animate a few of the variation parameters in the sketch material. You might also want to use UV mapping instead of frontal so it doesn't look like the object is moving through the texture, but maybe that's what you're going for.
