Hi Marcus, just in case you know here a solution, too:
I find it meanwhile very convenient to use another Zplugin function:
To increase and decrease brush size by a hotkey.
I have assigned (like photoshop) the “,” to making brush smaller and “k” to making brush bigger (I wanted to use "."for making brush bigger but somehow it is not possible to use the “.” for any hotkey.
This is very good in workflow, because you can hold your pen and your eyes static at the same point you are working on or change the size WHILE working.
Is it possible to assign in the same way something for increase/decrease Focus and maybe also Z-depth?
Maybe I could clone that plugin script and adapt it once to focus and once to Z (and for some users maybe also RGB).
p.s. I haven’t ZBrush here on this computer, but I think the “increase/decrease brush by hotkey” function was somewhere on the top maybe at “Misc”.
