In Watchmaker app (3.2.0) a shape with outline fills with outline color when Opacity = 0.
-Create a Square shape
-Insert Shape effect Outline
-Set Opacity to 0
Entire square is filled with outline color.
I have a square with outline which pops up only in special conditions. So the Opacity is driven by a formula.
When I send the face to my watch while opacity is 100 then it works perfectly. As soon as the formula sets the opacity to 0 the square disappears including its outline.
But when I send the square to my watch while opacity is 0 then the square will be filled with the outline color as soon as the formula changes the opacity from 100 to 0.
