Wondering if anyone can help me here. I'm trying to make a brush created from a gradient, so that I can have a hard edge and a soft edge while I paint, similar to an airbrush and a mask except without needing a mask. I can make something that works, but it is unwieldy because it's hard to estimate where the brush edges will line up. I'm including a picture to explain what I'm hoping is possible. Anyone have any ideas?
