The difference between wet and dry brushes and

[terbas]

I’d like to know the difference between wet and dry brushes and also their implementation in the blender/smudge engine brushes. As far as I understand wet brushes have some paint on them already? I may be wrong. And for smudge, how is the effect given/achieved? How is a dry and wet smudge brush made basically?

afaik, wet brushes can pick some of the color from the canvas.

Each dab has a different color that is a combination of the underlying canvas color and the foreground color you have chosen.

you can tune how much of the canvas color is picked for each dab, by changing the opacity and the color rate (they have different behavior, experiment to understand)

the “radius” determines if the canvas color that is picked comes from a single pixel or is the average color of an area (with that radius)

(what I’ve described is the “dulling” mode. the “smear” mode is different, it seems to drag the canvas color instead of mixing each dab.)
