iMac Tahoe. Why do I have to brush twice to get solid coverage? Flow is set to 100%. Hardness is set to 16%. Spacing is 11%. Shape is 100%. Size is 397 pixels. Every time I paint on a mask, I must paint twice to get solid coverage. I'm using a Basic Round Light Brush. What do I have to change to paint ONCE and get 100% coverage? AP2
