I have a some vector artwork in a single shade that I am trying to add highlights and shadows to (trying to achieve cel shading effect). I thought that the paint bucket tool would be the way to do this, basically draw an intersecting curve on the main shape to isolate where I want the highlight or shadow, and fill in the desired color. However the resulting fills don't conform to the shapes of the lines that are supposed to define them. (See image below - the fill shape in dark gray has a ton of extra points, and zigzags wildly.) Am I doing something wrong? Is there a way to fix this (aside from manually adjusting all the points to fit within the boundaries I had intended) Is there a better way to add highlights and shadows to a base shape?
Thanks in advance.
