How does krita make hollow brushes (the kind in MediBangPaint)?

How does krita make hollow brushes (the kind in MediBangPaint)?
I know a similar effect can be achieved with layer style strokes.
But how to make such a brush?

Here is a demo video of the hollow brush.

【MediBangPaint Pro】中空笔刷描绘头发ver 2.0_哔哩哔哩_bilibili

edit.
I found out that I did stupid things.
I just realized I had accidentally chosen the wrong blending mode for the brush tip earlier.
This caused me to think that the tip of the “Masked Brush” couldn’t subtract the brush tip.

The “Masked Brush” tip does subtract the brush tip.

I read the comment, one has explain something about the function:

有个保持边缘，点了以后画就不会交叉，但麻烦的就是如果你撤消或者擦出或者换其他笔刷就会退出保持边缘。并且保持边缘的效果仅对当次开启期间内画的有效，意味着你开启前和关闭后哪怕再次开启的中空笔刷的痕迹还是会相互覆盖。

There’s a Preserve Edge function, drawing won’t get overlap after using it, but the tricky part is that if you undo or erase or switch to other brush will quit Preserve Edge. Plus, Preserve Edge will only work in the time you turn on Preserve Edge, meaning the strokes will overlap when turning off and on the function again.

Simple. It don’t.
You can see others wanting this kind of effect in this thread:
Feature request: “Watercolor edge” (dark edge) to brush stroke

The concensus was that a good and awesome addition to Krita, one that would give this effect. While allowing much more interesting brushes was a ‘minor brush’. Basically drawing a brush inside another brush. Here a topic with the feature request:
New concept: minor brush

If you don’t want to read the topics above here is the saddest part. A ‘real’ dual brush was implemented in krita, but scrapped for a clone of Photoshop’s mask brushes.

New concept: minor brush

It actually did work fine, but it wasn’t the same as photoshop’s dual brush, and in the end, my work was scrapped and replaced by masked brushes, which are a clone of photoshop’s dual brush. And no, that didn’t make happy… I’m not going to resurrect that old code in any case.

I mean, how to make hollow brushes in krita.
I tried the “Masked Brush”, but couldn’t make the “Masked Brush” tip minus the brush tip to leave an outline.

Yes, I know that. But I don’t think it’s possible with Mask brush.

I just saw this today, and those are pretty interesting brush combo. bummer it got scrap for a more ps style approach. i could see tons of crazy brushes coming up from those concept.

Edit: I read wolthera’s reply and it seems there was an issue with implementing it thats why its scrapped.

[Daishishi]

Yeah, but in response to Wolthera’s comment Halla, the Lead Developer, respond saying it was working fine. So I tend to believe her. Just wish both approaches where kept.

It is good to have a PS like dual brush. It help many ‘outsiders’ users porting their brushes, and it has it own merit on this type of masked brush.
A ‘minor brush’ / real dual brush would also give such a edge to krita. I don’t believe any other app has a brush like this.

Krita would be the ‘edge of the spear’ in this regard. Unique in this type of brush. But alas

Yeah - i saw the samples and im like , i can see different possibilities - not only the watercolor edge [which would probably a soft brush with altered curve, and solid brush stack together in multiply] but bunch of different chain like brushes, and also the stroke brush - will all be accommodated. I hope it get revisited again.

I read these.
This is really sad.

Thanks for your reply, now I’m trying to use RGBA to make hollow brushes.

Just come up with a very rough idea
Paint on selection mask → fill color → adjust the selection size → remove the inner part

now you are making me want to try and experiment with this to see if something comes up.

Thanks again, after I carefully read the topic mentioned in your reply.

Currently in krita I do that with layer styles but a brush would make things so much faster.
