Hello everyone,

I started to look into Krita and I really enjoy it. I normally work with Sai and I'm always a bit sad that other programs don't offer options to customize your pen ductus to mirror Sai's amazing properties. The reason for that, I believe, is that they don't offer means to adjust pressure when you end a stroke which differentiates Sai's brush behaviour even from programs like Clip Studio Paint. While optimizing your stroke initialization (PressureIn) is a common feature, optimizing pressure regulation when you end a stroke (PressureOut) is generally overlooked. (Sai doesn't actually let you customize this either. However it's part of their inherent brush properties from the get-go. Sai 2 doesn't have it by default anymore (it's more like CSP now) but you can turn it on again under Options -> Preferences -> scroll down. : ) )

Here is an example of what I mean:

https://sta.sh/0ml55tokrf6 (Krita)

https://sta.sh/0148dn5jeu3b (Sai)

While the beginning of the stroke is under my complete control, the ending is very hard to define. It's more like dragging a blob of paint along.
This makes anything, that requires defined outward strokes and sharp line endings not as pleasant to do as in Sai imho (Lineart, eye lashes, leaves, grass, hatching, etc. etc.)

When I adjust Krita's PressureIn, the beginning a stroke feels exactly as smooth, sharp and dynamic as in Sai. If you could mirror this setting's sensitivity for the stroke finish then I believe you would end up with pretty much a Sai-like brush. I think this would give Krita a huge edge. Also, it would enable Linux users to have an OS native drawing program that gives them one of Sai's essential tools without having to simulate Sai itself via Wine or other virtual machines which can be quite tricky, especially for inexperienced Linux users.

It's just a small feature (I think...? orz) but I believe it would make a big difference. Maybe there is a chance of implementing it in the future?

Best wishes

Hapda

(For appearance - workaround, I enable the "Tool Options > Stabilizer > Finish line" option)Yes, as a regular user I agree.

It would be a very nice feature.

Hey,

thank you very much for your tip and the thread! But to be honest, it's not quite the same as what I was trying to explain. (Btw please don't feel weird because I'm writing so much. ^^; It's not supposed to come off as aggressive and a lot isn't even related to your initial reply anymore. It just got me thinking and I think it helps me to specify more generally what I think sets Sai apart technically. (Though, I am a layperson, so there's that...) So this is not an avalache of a reaction to your reply in particular.)

Krita's stabilizer works really well but the "thickness distribution" is still very asymmetrical with a shift towards the ending of the line. The stabilizer makes it look much sharper and better-looking but the basic shape (and with this the underlying "pressure control" issue) remains. The weight distribution of the Sai lines (https://sta.sh/0148dn5jeu3b) is much more symmetrical, with the thickest point being more or less in the center, while the ending of the line fades almost as evenly as the beginning.

At least in CSP the start/finish correction (mentioned in the thread) doesn't do the same thing as Sai either. The stroke's shape still remains in a similar shape (and for some reason CSP makes lines thinner when correcting them, which really disrupts the drawing process imho as it makes accurate drawing, esp. while being fast, much harder orz).

I don't know what kind of magic water Sai is feeding its stabilizer or basic brush control that makes them so hard to mimmick but I do believe it has something to do with a very direct, symmetrical pressure control.
Even on non-lag stabilizer levels such as 7 (i.e. quite mediocre considering Sai has 15! steps above that) the lines turn out better than on high level CSP settings with CSP having the typical stabilizer lag whereas at level 7 in Sai I have an absolutely intermediate, lag-free and lightweight drawing experience.
When I turn Sai's stabilizer to 0 my lines look more "draggy" (weight dragged to the end of the stroke) but even here it's not as pronounced as in other programs and fades pretty quickly if you turn up the stabilizer just a bit higher again (4 -> decent, 5 -> close to gone). This makes me think it's not only a stabilizer issue but an interaction between how Sai fundamentally translates pen input into brush strokes which then are perfected by the stabilizer.

Whenever I customize pressure I automatically think across programs "Great, I managed to perfect incoming pressure, now if I could just apply the very same settings and values I defined to fading pressure". And while this is of course not exactly an accurate technical measurement ( : P ) I think there may be some truth to this reoccuring automatic urge for wanting to customizes it this way.

Not sure if I'm understanding the goal (sorry for that, I'm not that experienced on making presets), but it seems like you want to modify the curve of the pressure, not the type of setting to use with the pressure, something like my pic would give the same pressure at the beginning and at the end of the stroke, (note that nothing else needed here but only the pressure parameter with the "arch" curve).

Note that stabilizer, although can alter the stroke, is only meant to delay and correct the shakiness of it, if you play with its numbers, the stroke shape should still follow at some extent the pressure curves thus, don't use the stabilizer to set the stroke, just go to the preset settings and do the modifications there.

Again, not sure if that is what you were looking for, hopefully it gives you a least an idea of where to modify the strokes.
