Brush tips with changing pattern

Hi there,

does anyone know if there are brushes in Corel Painter 2019 whose pattern of bristles changes with every new brushstroke? Apologies if there are and I´m simply too stupid to find them.

Painter has come a long way since it´s beginnings, and the possibilities to add randomness to the brush tips are great, but there´s still something I´m missing, and that´s a brush whose pattern of bristles changes with each an every new stroke. The lines single bristles create are still a bit regular and repetitive for my taste.

Here´s an idea - and I have no idea whether that´s technically possible:

Imagine a brush tip with 10 individual bristles. Imagine each of those 10 bristles taking on a different thickness with every new stroke of the brush. Everything of course within certain limits, that is relative to the overall thickness of the brush ("overall thickness" meaning all 10 bristles combined). 

That by itself would provide a changing pattern of bristles with every now brushstroke. Combined with already existing ways to add randomness to brush tips in Painter would add more organic appearance of a brushstroke.  

Take this one step further: Imagine a brush with 10 groups of bristles, each group containing 5 individual bristles. The same idea applies now to every individual bristle in each group. This way a brush would create what would initially seem like a brushstroke consisting of 10 individual bristles, at closer inspection those individual bristles would each create a unique pattern in itself every time you set the tip on paper.

I´m curious if this would be technically possible, and if it would create the desired result.

  • Hi Pixelpusher,

    It's definitely worth trying brushes based on the "Dynamic Speckle Bristle" technology...they may not do exactly what you describe--but I think it's going to get you very close!

    They are very expressive and many of them do not leave the exact same bristle brush mark from stroke to stroke (something many Painter brushes are quite good at, especially these!)

    Here are some specific variants to try:

    "Bristle Soft Cover Pressure Expression" under "Dynamic Speckles"

    "Real Bristle Drip" under "Dynamic Speckles"

    "Real Bristle Soft Cover", also in "Dynamic Speckles".  For this brush, I find it works really well if you make a minor edit to it:

    1. Open the "Real Bristle" panel under "Window > Brush Control Panels > Real Bristle"

    2. Change expression from "Rotation" to "Bearing".

    This helps the brush rotate nicely on a Wacom device that supports tilt and bearing, such as an Intuos or Cintiq.

    Also, for each of these brushes consider playing with some settings in the "Dynamic Speckle" panel under "Window > Brush Control Panels>Dynamic Speckle". For example, play with the "Scale/Size" slider, or choose an expression for the speckle size such as pressure.

    For the 'random bristles between brush strokes"...try adjusting your "Speckle Randomness". Again, you'll see some subtle variability that should help with a natural look and feel for your paintings. Increase the smoothness and decrease the spacing if you are seeing too many 'speckles'.

    You can even randomize the speckle opacity...depending on the look you want, this can be quite fun to play with.

    Hope this helps!
