Hi friends.
Almost 1 year later, after trying over 5 different versions of ZBrush on Wine-Staging, Lutris, and Bottle, pressure sensitivity was still not working correctly on Linux with any graphics tablet.
I asked around on other forums and did some research, and everyone seemed to have the same problem. Additionally, there were other errors that also occurred on Linux, such as window transparency, where the alpha did not work to see the desktop background, but it did work on Windows.
Fortunately, I continued learning to sculpt in Blender, and although Blender can’t handle as many millions of polygons as ZBrush in sculpt mode, Blender is easier and works better for me, so Blender for me is perfect and I’m happy with it.
I just wanted to inform, in case it can help someone!
