Deprecated, the Masked brush? i am not agree because this quit lot of creative possibilities, at least for Brushes. More blending modes for patterns? Tey will be welcome. We have to be very proud of what we do with until now, subtract and multiply. (lightness mode for example needs more exploration. I save this thread to read later, so no flame 
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.
+1 for the Height blending mode for brush textures.
It will come eventually, at least I hope. We just need more patience.

Hi, I’m closing this thread because this is a bit confusing when there are multiple threads about the same thing. The other thread has some new ideas how to do things so I’m closing this one and all the conversationg should go to the other one.
Also I think we already established that the new mode would be good to have, we just need a method to implement it, and then, well, someone needs to implement it 
Old investigation results (I had in a “draft”, it’s a bit outdated now since the other thread has some other investigation but I don’t want to let it get lost):
I’m not sure what “Color Burn” does… other mentioned modes are in Krita so it would be ok to add.
Regarding the Height stamps: I must admit it did take quite some time. However I think we might need to do this exercise again 
I think the gradients were already dithered:
Moreover, since I noticed there is “Hard Mix” color in both Krita and your results, I tried to get the same result with layers and… I don’t think it works? I mean I get this result:
While yours (from the brush) is skewed and has noise on the bottom between the balck and white parts.
