Pen pressure settings

[Srnec]

I`d like know how to change pen pressure settings, because I`d like to do some shading, but with more pressure the brush goes darker and thicker...
I will be very glad if somebody will tell me how and where to change that settings to: more pressure -> darker color (size of the brush will be the same or just small difference)

and I have one anotherquestion...
technically, in default... dakrkering the color with more pressue affect color opacity? 100% pressure = 100% opacity color ?

HI
ok - as you probably know - in painter not all brushes work the same

however in menu window>brush controls, the settings you want are in general and size - set the general/opacity expression to pressure and the size expression to none as shown below - tweak the opacity slider for variability

you should experiment with all the settings [this will take a while ]

also if you have not done so set brush tracking in edit>preferences menu
