What brush tools/settings do you use/whats the correct way to create lineart/vectors or brush tool?
In sai: I work with .7~1px pen (the first tool in the box) to ink. And sometimes 3~7px to add line variation. I use the next 3 brushes (to the right of the first tool) in combination to paint/cg. They are all usually in standard setting, and occasionally I’ll change the opacity to get lighter strokes. Correct way to create lineart: there is none. Lineart can be thick and thin, messy and blurry, or sharp and inconsistent if you like. The important thing is just to focus on what you want your piece to look like, and whether that lineart is the style you’re going for, otherwise you’ll get distracted.
