Please add a simple fall-off option in paint mode.
The idea is that the user can take any alpha, texture, or brush and be able to fade out that alpha or texture from the outermost edges. So the borders of the alpha are not visible when we stamp it.
Whenever I want to use an alpha, I have to do this manually in Photoshop for every alpha or texture in order to use it in substance painter.
Like in Zbrush, we have an option called Focal shift. It feathers out the alpha so that the harsh border of the alpha is not visible.
