I'm using the digital watercolor ("soft diffused brush"-- no modifications). I want to paint over a layer and exceed it slightly.
However, everytime I exceed the previously-painted part of my layer, it acts like the paper's white instead of clear.
The first attached pic is when both "preserve transparency" and "pick up underlying color" are unchecked, and also when only "Pick up underlying color" is checked (same thing). The 2nd attachment is when only "Preserve transparency" is checked.
I'm not sure what other option to use to get the white to go away. At least it looks better in the 2nd (perhaps only the areas with a tiny bit of mostly-erased color are affected?) but not good enough.
