I´m using Photoshop 2025 (german version) and there is no way to use the action ring with the dialpad in order to rotate a Photoshop brush tip:
- if I use the action ring and your predefined brush tip rotation, PS doesn´t rotate the brush, but switches to another brush tip.
If I set up the action ring manually and assign the left and right arrow keys to the dialpad (which are the shortcuts for brush tip rotation) , that works actually. But you cannot see the brushtip, as long as the action ring is visible!
