I have been experimenting a bit with the brush engine in Krita to get to understand it better. I like brushes with hard edges but also an organic edge, and after some trial and error I got a few brushes that work quite well for me. I based these on a couple of brushes from the HC concept set. I liked those brushes, but I don’t like the soft antialising in shape and texture.
I created a liner brush with a size/pressure variety, which I maily use for drawing freehand or to draw shapes as it creates a nice irregular edge. I also created a round brush and a block brush, which are useful for blocking in big areas and roughing. These brushes have texture which becomes more visible at low pressure. By setting the the offset of the texture to random, it is possible to overlap brush strokes without having the pattern overlap in the same way, making it more organic. The key to making these brushes hard edged was to set the texture blend mode to hard mix.
I hope you find these brushes useful and would love some feedback. You can change anything about these brushes in whatever way you like.
