I have a new Intuos tablet which came with Corel Painter Essentials 6. From the beginning, I have been unable to use between 40-60% of the brushes. I am on a Imac and have reinstalled the Wacom driver, reinstalled the painter software, used a test user profile and followed every suggestion of the Corel tech support to no avail. At best, I have occasionally been able to get the problem brushes to work for a few minutes, but then they quit (usually after trying to change the color. Is this a Corel issue or a Wacom issue or both? Any ideas?
Please restart it, and try to update it.
I have Windows, but Corel support on Mac is terrible. If you look through posts on this forum, some have had to roll back to the previous OS for Mac to get Painter to work right. Issue you describe probably not Wacom. As sachin said, make sure you do this update patch-
Only other suggestion is to do a clean install using an uninstaller listed here that will remove all files and entries, in case any are corrupted and not removed with regular uninstall.
A question for you, Maureen--do the brushes paint as expected with the mouse? If the majority of brushes are painting with the mouse, but not with your stylus it will help narrow the problem a bit.
A couple years ago I had an issue with many brushes not painting--turns out the stylus tip wore very quickly and was not transmitting pressure through to the brushes. I replaced the tip and all was well again!
