I love this program a lot. But one thing is really bothered me is the ERASER in Corel Painter.
Eraser, as an essential tool for painting I'm shocked how few variations of eraser Corel Paiter has. it's 2020 most digital drawing software all support eraser share brush settings of all other brushes. Or you can just change brush color to transparent works as same as eraser. But in Corel Painter you CAN'T do either! You can use only those several very dull no texture no brush hair etc.erasers. I just want to use the eraser as same as my other brushes. Come on Corel Painter make your product greater by improving the ERASER.
As Stephen wrote below there are many methods to customize the Eraser. Then you can save it as a new Eraser Brush Variant. So this will actually make it a brush variant. In the past this would hinder my workflow speed a little because I like to use the shortcut keys to quickly switch between the Brush Tool and Eraser Tool to do a lot of quick sketching/erasing. It used to be hard to switch quickly between two brush variants however (color applying brush variant to eraser brush variant) but recently they introduced the ability to switch between brush variants with a keyboard shortcut - look under the Brush Menu for "Select Previous Variant"
If you go into Preferences, you can program this "Select Previous Variant" to a keyboard shortcut such as "X" (for "exchange") and then you can switch between a "color applying brush variant" to an "eraser brush variant" pretty quickly. Or you can set this shortcut to your Wacom Pen.
I think Painter's eraser is just a different animal. I find there is a ton of customization you can do with erasers in this program but there is definitely a learning curve there. There are actually many, many variations of the eraser (limited only by your imagination).
