Wannabe Scientific Pointilism...
I warn you, this thing is extremely experimental and there is a severe lack of control...
BUT it’s fun!
What it does:
lowest pressure: line of dots with big gap
low pressure: loose spray of dots
medium pressure: denser spray with harder borders
higher pressure: very dense spray with hard borders and less width
highest pressure: line (of sadly roughly one thickness…)
ending on high velocity: brush- and particlesize to 0 (makes it possible to draw something like pointed lines…

Use with caution (like I said, it probably isn’t very useful…), have fun ^^
(Even free is too expensive...I should pay you for downloading this XD)
