It was working this afternoon. I went out came back and now it’s not working. The square bracket keys no longer size the the brush. I’ve spent two hours looking for a solution but no luck.
The bracket keys are working fine in other apps and as far as I can tell all the other shortcut keys in ZBrush are working fine. I’ve tried initialising. The Plugins/Misc Utilities/Brush buttons work when I press them with the mouse.
Thanks for any help.
