SUMMARY Pixel brush engine rotation stuck STEPS TO REPRODUCE 1. Create Pixel Brush Engine brush. 2. Assign stylus rotation to rotation. Tip shape should be not round. Quit to canvas. 3. Rotate the stylus in hands and watch cursor. OBSERVED RESULT Brush Cursor rotation stucks in certain positions. EXPECTED RESULT Smooth continuous rotation SOFTWARE/OS VERSIONS Windows: 4.4.7 ADDITIONAL INFORMATION
It may be that your stylus is not producing a continous and smooth rotation output. If you have Size controlled by sylus rotation and move the stylus steadily across the tablet while rotating it at a steady rate, what sort of line do you get?
Ha, Zaryuta! Could you check two things: 1) Make sure that "Precision" of your brush is set to 5 and "auto precision" option is disabled. 2) What is the model of your tablet? Are you sure you use Rotation, but not "Tilt Angle"? Afaik, real rotation sensor is only available in ArtPen stylises of hi-end Wacom tablets (perhaps my info is outdates). And "Tilt Rotation" in Huion/XP-PEN tablets has problems with non-smooth rotation near vertical and horizontal positions (last tested in 2019, perhaps something has changed since then).
I had found out what setting fixes this behavior! If I uncheck "Share curve across all settings" in the rotation tab, pen rotation behaves normally. I don't know if it's bug or not, but this setting shouldn't be On by default for sure.
Did you have another input enabled for controlling tip rotation in addition to the stylus rotation input? If you didn't, then this may be a bug. If you did, it's not a bug, it's a user settings error/misunderstanding.
In the rotation section only "rotation" is checked. All other inputs unchecked
I can sort of reproduce this with 5.0.0beta5 (0e4b844) Windows 10 Wacom PTK-440 + Art Pen (with rotation sensor) "Share curve across all settings" made no difference. Only Pen Rotation is assigned to Brush rotation Comment: When the pen tip is almost not moved at all while rotating the pen, very few draw events are generated. The brush (a 10:1 aspect ratio square edged brush, like a very broad calligraphy marker without fading) therefore generates a many-pointed 'star' or 'asterisk' shape rather than a circle. Could the cause of this phenomenon and the original report be that the brush only draws when a move event is received. If the stylus only rotates without moving, nothing is drawn, so the brush only draws when a tiny movement is registered? See attached file.
