Since I changed my old Intuos to a brand new one Pro, the brush rotation that I've got with the Art Pen is inverted. (Brush option/shapes dynamic/ angle ->rotation)
Do you know if there is a setting somewhere to control the rotation curve to invert it?
Or a PSUserConfig.txt command line that I can use ?
Basically if I turn my pen to the left, the brush turns to the right.
I asked Wacom and they replied that it's a photoshop issue..
I did a reset settings on the Wacom firmware and now the Photoshop brush rotation function doesn't work at all..
I'm working on window 7, photoshop cc 2015.1.2 with an Intuos Pro M.
Please update to the latest version of Photoshop(CC 2017.0.1) and let us know if that helps.
