Enhanced Brush Controls

I see this is an old thread that ​@angryf84 has woken up, but worth some input.  AFAIK we can’t rotate the texture in real time with the brush because of how it works. Dual brushes, or brushes with a texture essentially reveal a pattern.  They are doing exactly the same as filling a layer with a pattern, but with a ‘hide all’ layer mask, and painting the pattern by using a white brush in the layer mask.

It’s the same with changing size. We can set a dual brush to change size with pen pressure or fade, but the underlying pattern remains at the same size.  (Ignore the size jitter. I should have set that to zero.)

The problem with Fade is that we can only get the size to decrease.  I did try using a negative number, but it would not accept it.  Note: Fade is dependent on brush spacing, with each stamp of the brush reducing the parameter by 1.  The example below had a spacing of 1%.

We can control multiples of the brush with Count Jitter or Control. 

I’ve set Count Jitter to Pen Pressure in this example.  The upper pass was with the lightest touch I could manage with a Intuos 5. The lower pass using full pressure.

To smear you’d use the Smudge tool, which can use Strength Jitter It’s something I use to create explosion effects by dragging out from the centre.  I find strength jitter alone is not especially effective, and that it works better if you add size jitter with Fade or Pen Pressure.

There is a lot of power in the brush engine if you look into it, but apps like Krita (which is free) have better brush engines — although they still can’t rotate the pattern behind a dual brush.

All of these as well as being able to change the texture size that brushes use like you can in photoshop
