I suggest you refer to images from krita docs? I think in docs the advantage of brush mask tip don’t so obvious. In the essence it is an ability to change form/frame of the stroke on the go, blending pattern-tip modes don’t allow it. And why mask tip has 9 blending modes against 2 in tip/pattern interactions is some an enigma for me.
Consider to the main topic.
As I mentioned in parallel thread I have ‘mimiced’ height mode for ‘superflat tip’. (You need masked brush tip sized 1:1 with main tip but filled pure black and set it to “Color dodge” mode, and in opacity curve of masked tip set it 0 up to 50-70%. For the ‘fat’ brushes process is simpler since it have a thickness.)
Still it have a bunch of nuances and headacing during creation and modification. And I am not able to achieve the feeling I am goal because, as I see, of the core of substract mode that sort of downgrade or nullify effect of opacity/flow especially for the superflat tip. It sort of blocking fluency and slenderness between stroke interactions that I feeling in PS (despite it still hasn’t curves for brushes
) and especially CSP.
And, finally, what is really important we have the logic construction suggested by @hulmanen that may help developers to implement “Height” mode.
