Efficient painting brushes & smudges
Smudge "amount" is controlled by speed of movement due to the spacing being disabled.
Brushes I've been perfecting for a long time, intended to be used with brush opacity and flow at 100%. These are more pleasant versions/replicas of some of my favourite digital artists' brushes/marks and you can find some of their brushes online, but I always found them to be annoying to use, like requiring too high pressure to have clean marks or a hard edge, or having to do too many actions to soften an edge. With these you can achive clean marks with hard or softer edges, with very little pressure change. . And these will save your hands in the long run due to the lower pressure.
UPDATE 20.8.2021: Added 4 brushes and 2 smudges. For past year I've painted 99.99% of everything with only the chaoticChalk1 and the smudge smooth3 and using the mouse. These work just the same with the stylus too. Wanted a brush that somewhat replicates the inherent randomness of physical brushes which often make creating interesting smaller shapes much easier. Get the very clean chalk texture by using linear burn mode in the dual brush.
Harris1 smudge was inspired by the types of edges I often saw in John Harris' oil paintings, used this exclusively until I created the smooth3.
Some of the artists whose marks I was replicating:
UPDATED 6.5.2018: 15 brushes, 4 smudges as of now, will not write about each one, but there are new replicas and my own ideas which I use all the time
