I put me now times even more stupid than I am anyway. I have also only roughly skimmed the topic here.
Your Cintiq tool hopefully has, like most of these tools, the possibility to create profiles, so one for Krita, one for PS, one for CSP, et cetera, or not?
And now I looked for erasers in my currently activated bundles and found 7 different presets that only erase and it’s not enough for you to be able to activate such an exclusive eraser preset using one of these scripts and your Cintiq tool?
Okay. Is it because you might have to press a second button afterwards? I mean there was also a script or plugin that did that recently, something called “Temporary Tool Invocation”, could that solve your problem in conjunction with the “Ten Brushes” or the “Three Brushes” plugin? This “tool” did just that, a tool worked as long as the (or a) button (or whatever) was pressed and when released the previous tool was back. Is it something like this?
Ah, found it: Temporary tool switching
If it is something like that, then look here.
I haven’t read up there now, but on the quick found in the topic that the plugin works, whether it meets your need I don’t know.
