painting in the alpha channel with the erase color does not bring back the expected result. im just able to paint “white” (paint color) without being able to go back to “black” (erase color).
Did you ever figure this out? I’m having the same exact problem righr now with no solution in sight.
EDIT: Figured it out. You have to set the A value in the color to 0. Even with black color selected, Alpha is at 1. Set it to 0 and now you can erase. Slapped my forehead when I realized.
