SUMMARY I download Fizzyflower’s ULTIMATE MyPaint Brush Collection and test the brushes When I select a brush that is not an eraser. After turning on "eraser", it loses the other parameters. Only the radius takes effect. But when I select an eraser. When "eraser" is turned off, it is still an eraser. This is also true for the mypaint brush that comes with krita, so we can exclude the effect of bundles

As a supplement: When I switch tools, "blending mode" becomes selectable. When I select "eraser", it can erase the image normally. But when I check "eraser" in the brush interface, the "blending mode" will become "normal" and the brush will become a normal circle. Maybe krita should adopt the original "eraser" parameters of mypaint, it is also more powerful and supports sensors and curves.
I found it again today when I was organizing mypaint brushes. I have two guesses about it： 1. maybe it can support blending modes other than "eraser" 2. Maybe it would be better to use mypaint's own "eraser" parameter, because it can map all kinds of sensors by curves.
Git commit 93bf757c4e4e2bfd9e53eb6b31c8117cd98303cf by Dmitry Kazakov, on behalf of Carsten Hartenfels. Committed on 05/09/2022 at 12:15. Pushed by dkazakov into branch 'master'. Make MyPaint eraser use the proper brush settings When enabling eraser mode, Krita will use the default MyPaint brush settings instead of the ones the user has actually selected. This is unlike MyPaint, GIMP and Drawpile do it, which use the selected brush to erase. This is due to a setting that enables this odd behavior, which is not actually exposed in the user interface, meaning there's no way to turn it off. This commit outright removes that setting and makes Krita behave properly: use the brush that's selected and erase with it, don't switch to something else behind the scenes.

Git commit 1576bf60ae59947c2bb7131bd2e6c07be2427d56 by Dmitry Kazakov, on behalf of Carsten Hartenfels. Committed on 06/09/2022 at 11:12. Pushed by dkazakov into branch 'master'. Fix disabling blend mode combo for MyPaint brushes MyPaint brushes don't support custom blend modes, they always use what MyPaint calls "Normal and Erase". The code already made an attempt to disable the blend mode combo box to represent that, but switching tools caused it to re-enable itself, despite having no effect. This commit fixes that: the brush blend mode combo box gets disabled upon switching tools if a MyPaint brush preset is selected. It also adds a comment explaining the reason behind that rather non-obvious special case.
