I am using Painter 2023 and cannot control brush size properly with pressure with some brushes.
When brush expression is set to pressure I only get thin and thick lines and nothing in between as it just jumps between these thickness very abruptly. I have followed the guide in this document to set brush tracking but this does not resolve the issue: http://product.corel.com/help/Painter/540213829/Main/EN/Win-Documentation/wwhelp/wwhimpl/common/html/wwhelp.htm#href=Corel-Painter-Brush-tracking-and-calibration.html&single=true
Some brushes are fine but it's very noticable using Pencil 2B for example. The Stroke Preview shows a sudden transition from thin to thick line, not gradual like other brushes.
I am using a Wacom Intuos S, which works fine with Painter Essentials 8 but not with Painter 2023. I have updated to the latest Wacom driver but the problem remain.
If you can share a screenshot of what you are seeing, including any settings you have changed from default, it will really help. That said, here are some quick thoughts:
1. Have these brushes always been jumpy since you installed the program or did something change at some point?
2. If you made changes to the brush, save a copy of it for diagnostic reasons...select the jumpy brush and go Menu > Brushes > Save Variant and give it a name.
3. With the jumpy brush selected, check the settings under the "Advanced Brush Controls". Find the "Size" Panel. At the bottom of this panel there is a slider called "Size Step". What happens if you reduce the slider value. Is there any improvement?
Again without seeing the issue it's hard to tell, but at least here's a few ideas to start with.
Brush tracking is usually the culprit, so I'd experiment there more.
If really brush specific, compare brush that is OK with one that is not OK and figure out what is different and fix broken one. Or try making the desired brush work OK from the good brush and change good brush settings to make it like desired brush....change 1 thing at a time to see what makes it not work correctly to discover any problem areas.
Painter does not work with Microsoft windows pressure sensitive laptops. It only supports WinTab pressure sensitive tablets (Wacom). After much back and forth with Corel support, they told me it would not be fixed. The last version that I tried was 2022 and it does not support pressure or tilt. All other programs work fine with pressure and tilt. Try Rebelle by Escape motions it is a lot cheaper and works fine
