@tiar asked me to create a separate thread to make it more visible, so here it is 
I’ve made a tutorial on how to create RGBA brushes in krita on the go, without really stopping your painting. I highly recommend to try to come up with some ideas for it, as the new possibilities are really amazing.
Buig thanks to everybody who participated in creating this feature - can’t wait for more
Fantastic tutorial, wojtryb! 
Well crafted and clearly explained!
For some reason I have never thought about importing the brush tip straight from the current document, I have always gone trough the hassle of creating a new document 
That will save lots of time when testing!
(Also, lovely sight at hehe 1:11-1:12 
Super cool to see those brushes in such a great tutorial)
Thank you for such kind words 
sometimes I use different document too, to store those brushtips in a form easier to edit. But for instant idea and proof of concept, this is a bit faster 
Oh yeah, I download quite a lot of brushpacks to pick one or two for further editing and for available brushtips (gonna catch 'em all)
I guess I still haven’t checked the updated version. Will have to get it someday 
Thank you for the tutorial!
Woah, you’re welcome
Is RGBA the same as impasto?
Can a smudging/blending brush be made with RGBA settings?
Basically yes. RGBA is the official name of the type of those tips, while impasto describes the effect achieved.
In krita 5.0.0 or higher. It’s currently available in beta release.
Next crazy question: can you choose an RGBA brush and simply change it’s engine (from pixel to smudge in Krita 4?)
No, the whole concept of brush engine is that it’s basically a separate program, that paints strokes. You need to recreate it from scratch, as there are other options to choose from.
But once you create a brush tip, it’s available in both engines of course.
Ok, thanks. 
Ty for this tutorial. I’ll give it a go.
Starting a thread that shares brush icons for people to make their own icons with would might be useful.
I think I’ll make a few free icons
No problem!
That’s a neat idea. I always use the default brush icons and just recolor them with HSV sliders, but that’s aleays nice to have more opportunities.
i tried to make one:

added a new tip to RGBA preset
I need to play around with rotation (had it smoother before)
Well the official way is “Lightness option” I think, RGBA is what voronwe used I think, so it kinda got popularized here on KA, so now Ramon uses it in videos, and now it’s a very common but completely opaque to newcommers name for this feature 
RGBA doesn’t even make sense tbh, because it mostly uses (RGB) + A, instead of all R, G and B channels separately, like the Color Stamp option.
So it’s another “historical reasons” name I guess…
first part:
(literally first time even trying these techniques, brand new to photopea and i’m just playing around but happy with result)
check out my process: tachiko - Twitch
at 10 min into video its like i’m mixing colors
i get that its mainly the smudging, still I was surprised how much it blended. is that from how i made the brush tip?
its up now, it was encoding (i had just uploaded it)
You did a good job, but I would go crazy with the advertising panel on the side, that is a NO-GO for me, I don’t use anything like that.

Same here! (With the advertising - no want!)
