Hello everyone, I'm trying to create some custom brushes to use when painting over masking layers, but I cannot achieve my desired result. This is the new Image Brush I made (white on transparent background):
The layer setup:
What I want to use this for is adding/subtracting from a mask, but the transparency is not ignored in the process, resulting in something like this when adding to the mask:
As you can see the transparency acts on the mask layer as an eraser (I'm using the pixel brush), and the only thing that I want to do and can do is removing from the mask while holding down CTRL (to erase).
Is there a setting, or color combination in the brush image that I can use in order to have the desired effect of only adding or subtracting the brush shape, ignoring the rest of the image?
Thanks in advance for any help!
