Hello, I am really enjoying Krita but I have found a problem with the color smudge brush. If I click on the 'block-paint-tilt brush', I'm able to paint with my intuos2 and have a type of brush rotation to it (stroke matches direction that pen is pointing). Now, I really like this feauture and looked this brush characteristic up and found out that it is under rotation as 'ascension'. Well, I then applied this function to the 'color smudge brush' and this rotation will only work on some of the predefined brushes. Specifically I was wanting a brush that had more length than width so that I could have a type of flat brush. I cannot get it to match the characteristics of the block-paint-tilt brush.' Is this a known bug, or am I doing something wrong? If it is a bug, is there a fix in any versions?

For those who are familiar with corel painter, there is a similar function called 'bearing."

Thanks

-Ryan

Can you add your brush preset so we can look at to compare them.

Thanks for your reply. I used the rake_2 and A-4 Pin predefined brush presets for the color smudge brush instead of the autobrush . I then compared that with the normal default settings for the pencil-tilt-sketch. If you tilt the Pencil-tilt-sketch brush, it creates thin lines if you paint in the direction the nib faces, and broad strokes if you paint in the direction adjacent to the pen. This behavior is consistent with the color smudge brush A-4 preset, but not so with the rake_2 preset and others. Also the behavior will sometimes break with the presets that do work, making them behave the same as the rake_2 preset. The behavior that I am getting is that it will only create thin lines if the pen is angled horizontally and it will have no rotation effect if the brush is angled vertically, regardless of the direction you paint.

Hey Ryan,
I deleted blacklisted all the default brush on my install , so I can't help precisely about them. ( I use my own preset here : http://www.davidrevoy.com/article123/krita-brushkit-v2 ).
From what I read it seams you try to perform a 'size variation' on a 'bitmap brush mask' ( a rake like image , not a procedural auto-brush ) depending the tilt of the stylus.
Avec you tried 'Size' sensor, with Tilt X and Tilt Y ?
Because using rotation to vary size will be effective only if your brush is rectangular , and have a footprint rectangular with very different width and height proportions. If you use same sensor on a brush with a footprint more rounded, the effect might not be visible.

By the way, next week is the Libre graphic meeting in Madrid ; and Animtim, Boud, Ramon and me will share probably a little brainstorming meeting about the default presets set delivered with future Krita. For the moment it's an accumulation of various brush collected all along versions, and there is consistency problems with pressure , and behavior. Feel free to write here what you would expect from them. Every opinion matters.

THanks David,

Well I just had a lengthy reply, but my login timed out and it directed me to a page and deleted all my text. ugh, that's a bummer.

To sum up what I said, I verified the bug on both windows and linux versions of Krita. The solution is to use a different preset(like yours) in order to get fully working brushes.

And what I would like in upcoming releases is a brush preset that varies its bristle density based on the angle of the stylus (.I.e bristle density variation is greater where the tilt of the stylus is closest to the surface). This is very much like how a an actual paint brush would apply paint. The look of a stroke will look different depending on the tilt of the brush.

A way to get the above to work is to have a density modifier that groups up an images pixels based on a the angle of the stylus in relation to the tablet surface.
