Mypaint brush bug radius logarithmic size curve affected by basic size

[tachiko]

II want to adjust things like size and smudge intensity with changes in pressure. I adjust the curve and it works but then if I adjust brush size on canvas using (shift + pen motion) and i see that the changes I made are shifted up, such that the highest point I made goes to the top.

I’m kind of torn on even bothering with mypaint brushes. but there are some that could be of use if we could play with the settings more.

this water color brush is pretty awesome and could benefit from this bug fix: SLOS 023 Wet-Watercolor

i want the curve where i drew the red curve, but it keeps shifting up to top everytime i increase brush size from outside the brush editor

Edit:
I think the main issue is that Krita’s basic size paramater needs to be swapped with the log radius algorithn found inside Mypaint Brush Engine. Because the one krita uses affects multiple paramaters inside the mypaint engine.
