Description Ralek Kolemios 2020-08-20 03:55:48 UTC

I have several 'sketch' brushes which have a curve that barely ever reaches 100% unless I push hard, and when I want the line to be thicker I do push harder.
However when switching to eraser mode, it keeps the same curve and is thus nearly impossible for me to fully erase a line, since the eraser also almost never reaches 100% opacity. I have to push very hard to erase a line completely, and even go over it several times. I've started getting hand cramps from having to push so hard.

"Separate opacity for brush and eraser" setting doesn't help, because I want the dynamic range of opacity available for my actual brush, while the eraser version either has a separate curve altogether, or simply ignores the pressure curve and goes by the opacity setting. (Maybe a toggle to ignore the curve?)

Modified Input Pressure Global Curve

If you find that you need to apply a large physical pressure to the stylus to get 100% pressure output and this pressure is unconfortable for you then you can modify the tablet pressure response in:
Settings -> Tablet settings. 

I attach a screenshot of the curve I use to give a lower physical pressure required for 100% output, with fine control at the low pressure end. The exact shape of the curve is easily modified to suit personal preferences.
