Problem description: When the tablet is pushed hard so the brush size reaches its maximum size additional pressure will cause the size to suddenly jump to a small size. (see image below)
Actually probably the reason why I have not noticed the pressure issue is because it only appear when pushing unnaturally hard with the Wacom. Pushing that hard with my Cintiq would quickly destroy my pen nib. However, it does exist in version 2021.1.1 as well as in 2021.6.6. My guess is that it should not be a Linux error beause pressure works well in other apps for example Krita. However, there is obviously some incompatible number translation between Linux-Wine-ZBrush.
To avoid the problem either you simply press lighter with your tablet or do the following tweaking. See the Brush settings in the image below.
Additional Tablet Pressure tweaks with Linux
These adjustments you can experiment with, however I was not able to get rid of the error defined in the problem description (see beginning of this post) except by tweaking the brush in ZBrush.
The following commands require: xsetwacom
Get the name of your device with the following.
xsetwacom --list devices
example:
Wacom Cintiq 22 Pen stylus id: 8 type: STYLUS
Wacom Cintiq 22 Pen eraser id: 12 type: ERASER
A very light press with make a mark for example a thin line
xsetwacom --set “Wacom Cintiq 22 Pen stylus” Threshold 1
Alternatively require some additional pressure with make an initially stronger mark
xsetwacom --set “Wacom Cintiq 22 Pen stylus” Threshold 250
Interpret pressure lineary (recommended)
xsetwacom --set “Wacom Cintiq 22 Pen stylus” PressureCurve 0 0 100 100
If you prefer a softer feel.
xsetwacom --set “Wacom Cintiq 22 Pen stylus” PressureCurve 0 5 95 100
If you prefer a harder feel.
xsetwacom --set “Wacom Cintiq 22 Pen stylus” PressureCurve 5 0 100 95
To read the settings as you log in to your account you can place the command in your users main folder in file “.bashrc” (hidden) in the bottom line.
To get rid of the “lines” rendering error in version 2021.6.6 the library override vcomp140 (native, builtin) can be used.
To get decimation master to work you probably need to adjust your preferences regarding decimation first (threads and dll).
I am running Debian 11 with KDE and Wine 6.0 stable (downloaded from winehq) if you want to know that.
There’s almost no pressure sensitivity, there is some (maybe I’m not sure), but it’s barely noticeable, also size sensitivity doesn’t work, so I have to change brush size way too often.
