Per the title, I am wondering what the exact difference is between smudge colour and smudge length, as the description in the tool tip is slightly unclear. What exactly is the “smudge colour” by definition? How does this relate to the canvas? The SC tool tip states that you can paint with the SC instead of the brush colour, and the SC is slowly changed to the colour you are painting on. Seems straightforward enough, but the smudge length tool tip states that the SC is slowly changed to the canvas colour. Is that the white base canvas (or whatever other background can be set, like paper texture, ect.)?
Further, my questions about Dab Angle came about as I am trying to create a semi realistic flat bristle brush as might be found in Photoshop or Krita. As I’ve heard before, this particular task is difficult in MyPaint, but I’d still like to give it a try. In my experiments setting a basic brush to have a single dab (approx 0.2 per actual radius) adjusting the Dab Ratio appears to make the stroke fly off the canvas. Why? I’m hoping a better understanding of what these settings are designed to accomplish individually will make brush design easier.
