Possible to simulate thinned streaky oil paint brush?

Is it possible to make an oil brush that has thinned out paint as above? I can make a brush with streaky bristles, however after two or three strokes the canvas will be completely covered in paint, where as the bristles of a real brush will continue to move the paint aside and paint new streaky strokes over the old one (see the bottom section of the picture above). I guess I'm asking if it's possible for a brush head to capture not only the black pixels, but also the white pixels of the alpha?

Thanks for the revolutionary software! I love that it's capable of doing 90% everything I've ever dreamed of in a digital painting program.

Just to clarify... You want a brush that instead of layering strokes on top of each other (1), it sort of erases or pushes away paint underneath as you overlap the same spot (2)



I agree. That would be awesome.
 
I kind of figured this out. If you create a brush with dual brush enabled with blend mode of subtract, you can get some weird effects. When using paint and blend, or paint and mix, you can overlap brush strokes and not keep adding opacity.



Here is a wet bristle brush I made.
 
interesting, I am too interested into such brushes
 
Yes! This is exactly what I mean... however, controlable with brush pressure. Like: heavy pressure overlaps brush strokes and light pressure pushes paint aside (or vice versa according to how you set up pressure curves)!
 
thanks for the brushes, I like them very cool.

I think you could explore using the "Sumie bristle " in the ink default and past it in the oil. Adding your effects to this default brush might create natural brush strokes too for oil paint. I ll try to do it myself when I will understand how you managed to create those first XD.
 
I tried using your brushto the sumi, not sure if I succeeded but it s cool effect. Thanks your a genius Gurujo
 
You can either have the brush strokes erase each other by using Paint & Mix, or Paint & Blend, OR you can have them build up by just using regular Paint mode. I don't think you can get that variation with pen pressure. I have switched my keyboard short cuts so all of my paint modes are accessible with my left hand (ZXCVB), without looking.
 
Hey lolozori,

I'm glad you like my brushes. I've spent a lot of time experimenting with this brush engine.

You cannot create this fake water effect in Oils & Acrylics. Only in Express Oils. I tried. This is because you need to select the option for "Use for Stroke" in order for this to work.



But, that option is grayed out for Oils & Acrylics brushes (below)



Side note: Did you know that you don't have to recreate your brushes for different categories? If you made a cool brush in Express oils, just right click on it > copy brush preset > navigate to your oils and acrylics tool > right click > paste brush preset.


=================================
Here are a few tips for your Sumi Bristle brush:
1. You don't need 3 brush tips. Delete the third one.
2. You have a good idea in using the same brush tip twice, but flipped upside down on the second one. But if you want the hard edge to show up in the same direction no matter how you make your stroke, you have to choose "pen tilt" instead of "pen pressure"




With pen tilt, the hard edge will always be on the same side, and if you want to change the direction of the hard edge, you have to actually tilt your stylus in the opposite direction. On one hand your strokes will be uniform, so you have more control, but its awkward to paint the other direction. With pen pressure you get variability but with a lack of control (unless you keep in mind how to start the stroke ie-left to right for hard edge on top)

Cheers
 
Bumping this back to the top because I would love to see this featured in Rebelle 8. Perhaps by adding a feature in the brush engine or Oiliness Slider (or perhaps a "Shovel" or "Viscosity" slider) that designates how much paint will be "shoveled" away with a new paint stroke. It would be cool to tie it into pressure sensitivity using a Curve Editor. It's hard to get streaky paint brush strokes when the streaks will be covered up by opaque paint within 2-3 more paint strokes. In this painting, an example can seen in the yellow of her sweater, the brown of the table behind her, and the red blanket beneath her head. The paint has a different viscosity, which allows a stroke to "push through" the paint layer underneath:
