is there any paint or PASeq presets that are available that can create something like this (attached)? (very deep brush stoke depths almost like impasto, very loose, random strokes with texture.) I especially like the second look for it's loose look and randomness and texture.
I am sure there are loads of Factory Paint Synth Presets that work in the area you are looking for. Experimenting with existing presets may give you what you want.
I am going to see if I can attach some of my own Paint Synth options here in this thread.
The finger paint folder here is some experimenting with - literally - a finger paint like experience. Some impasto like brushes here might be a good place to launch some experimentation:
The collection of oil like brushes here are all meant to have some oil like density. Some are auto paint options most were developed to apply by hand:
Anything with "gumball" in the name is going to have some thickness...
As for the example you like best in the images you attached... Maybe some MultiPen options? Something that will toss around several brush heads with each stroke.
